1. I am forced to pay subject to a ‘time’ base rather than a ‘use’ base.
To me, the value of a piece of software is in its utility (Use) not the fact it is installed on my computer.
If I had to ‘time-base’ subscribe to each of the pieces of software that I might need for only a very short period of time each month (there are about 25 separate programs. Some I use as little as 10 minutes per month, some only a few times per year.) the expense would not be cost effective. Other than my Browser (Email and Internet) nothing I have on my computer sees constant high usage.

$120 a year for something I already have - LR6. Do I really need every little tweak that Adobe adds to LR? No, I don't. If I stop paying, I lose LR. For me, it's a choice of paying $120 a year or paying nothing. LR does all I want it to do. If I were doing processing as a business, I might be tempted. Maybe. There are now so many good alternatives to Lightroom for under $100.

Quicken is now selling by subscription. The $60 version I got years ago will last me the rest of my life. The alternative is to pay them $90 every twenty-seven months. Pretty soon, almost everything will be "Pay Forever," but I'm resisting as long as I can.

Before you make bold statements (Like Adobe holding your photos hostage) you need relook at how the package works. It works identically to the older versions of Adobe Lightroom/Photoshop. All images are stored (in their original RAW/NEF/JPG or whatever) state on your C: D: or what ever local drive you decide. All of your sidecars and adjustments are also stored locally. YOU HAVE ACCESS TO ALL OF YOUR PHOTOS just as before. What you lose access to is the ability to make adjustments and corrections to those image in an Adobe environment. I can still open everything in Nikon Capture NX, Nikon View NX, Portrait Pro or ANY of my other photo manipulation programs. I just can NOT use the Adobe. The file structure is the same... I have an F: location that is a large drive with all of my photos arranged by dates (2015-1-12 for instance) with all of the photos taken on that date. I can go into any of those folders with a non-Adobe product and make adjustments. The only issues are that NONE of my Adobe adjustments will appear because they are in "untouchable" sidecars".
Yes, I had Adobe 5 (and still have it stored away) but because my Lightroom CC is ALWAYS up to date, I haven't needed it. It is installed on the D:drive of my computer and I can ALWAYS go back to it if I need to... And yes, it will not recognize any of the updated edits done by Lightrooms that are newer than that version but my Photos are NOT lost or even misplaced. Yes, I would lose a lot of the time that I spent editing those photos, but as we've all said, Adobe is NON-DESTRUCTIVE.

Oh, and by the way, having worked in the IT field (my degree is Electrical Engineering/Computer design and I worked from 1978 until Jan, 2002 in that field) I totally understand that you DON'T own any software. Try reading the EULA on them. You are only renting them and the producer makes no promises as to their functionality.
So, personally, (and as someone who paid $100 or so to Adorama or B&H, don't remember which, for Adobe Lightroom 4 and again for Lightroom 5 (hmmm that's roughly $200 or two years or so of Lightroom rent) before I subscribed to the cloud. Yes the Adobe Cloud for Photographers is $9.99 per month and yes it does come to $119.88 per year. But, what do you get for your $120 per year? You not only get Lightroom, but you ALSO get Photoshop, ACR and Camera RAW. You also get 20gb of storage on their cloud, constant updates to the latest and greatest, and the ability to install those programs on as many computers as you want, as long as only two (2) are logged into the Adobe Cloud at any given time. I have it installed on 2 desktops and 3 laptops. You can also use that 20gb of Cloud storage to pass your work from one computer to another for further work. This lets me pass photos to my wife if I want her to fine tune a photo that I've processed in Lightroom or she can pass something to me if she wants me to work it in Photoshop. The really big thing for me is that I can take my camera, laptop and equipment to a hotel or motel on an assignment, take the photos and upload them (I also have a large WD Cloud Chassis and drive) to my WD cloud (I could use the 20gb of Adobe Cloud but my WD is larger and is located in my house and keeps my Adobe clear for other things).
My point is that everyone panics about the software rental.. You really "ONLY RENTED" Windows 7, or APPLE (whatever version) Heck even the Apple Lisa OS was rented. Apple Dos, IBM DOS all were rented. You only seemed to "own" it. Try reading the EULA disclosure on the packaging. So, Adobe only formalized it and you are freeking over something that never changed. The only difference is that Adobe is giving you access to several thousand dollars worth of software for $120 per year and even more software for $50 per month or roughly $600 per year.
But, if you don't want it, fine... don't get it. But quit slandering, lying and/or giving false information and scare tactics to get others (who may not know either) to follow your lead.
If you have questions about Adobe and the Cloud...(please understand that the Cloud is a misnomer. The Cloud's main purpose is a delivery mechanism and NOT A STORAGE FOR ALL OF YOUR IMAGES AND WORK). All of your images, work, and Adobe files LIVE on your computer(s).
