Why did Canon quit putting viewfinder shutters on their cameras?

Would that exclude a UHH thread?

A large number, but not all. However some people ignore accurate information....

It's a shutter to allow you to keep stray light from getting into your viewfinder when you are not using it to shoot.

Several well known testers have tested the light leak problem and all report that no trace of light leak can be detected. Maybe it was a problem of yore that no longer exist or it never existed at all.
Yes, Iâm VERY familiar with the concept but have never read anything authoritative on that it really is a problem.

Here is an image, ruined by light leak through the viewfinder. 20 sec at f/11, ISO 200. Notice the red smear in the water.

If you were a amateur using a rangefinder, your keeper rate was
0% of the images where you left the lens cap on
5% of those images where you remembered to take off the lens cap
another 3% of the images in focus.

Your experience maybe. Certainly not mine. One simply needs to avoid absent-mindedness and always adhere to the same order of actions whenever operating a rangefinder camera. Then forgetting to take off the lens cap or adjusting focus before taking a picture will be the exception, not the norm.

On my D500 I use the shutter when using live view and remote realese

My old Canon A1 had one and it seemed to work fine. Now I have to keep track of a rubber cap to do what used to be done with the flick of a lever.
Does anyone have any ideas why a camera company would stop adding this feature to their cameras?

Most likely cost.

For most photography the purpose of the viewfinder shutter or eyeport cover ISN'T to prevent light leak issues, like the one illustrated in the above example. There's a set of light seals around the mirror of SLRs and DSLRs to prevent light leaks from effecting most images. If you see images effected like that, it may be time to have those light seals replaced.
However, an exception is a very long exposure in brighter light conditions. Those light seals aren't anything fancy (usually just black, open cell foam) and may allow enough light past during an extended exposure. Basically, it would be a situation where you're using a fairly strong neutral density filter, before the cover would be needed.
The other purpose of the cover or built in shade is to keep light from entering the viewfinder and reaching the metering system, which can throw off the accuracy of any exposure, while using an Auto Exposure mode. An example would be taking a self-portrait, where you set up the camera on a tripod and use the self-timer or a remote triggering device, and are using an AE mode without Live View or Mirror Lockup.
However, so long as you're not making exceptionally long exposures and the light seals are in good condition (they're not degraded and leaking), it's not necessary to use a shutter or cover:
1. When using manual exposure mode, so long as you aren't setting it according the camera's internal meter while your eye is away from the eyeport, while not using Live View (or Mirror Lockup).
2. With many (most?) DSLRs and some film SLRs that have their meter sensor array located in the bottom of the mirror box, instead of in the pentaprism (see light path illustrations at : https://luminous-landscape.com/understanding-viewfinders/).
3. While using Live View (mirror is flipped up, sealing off the the mirror box from light entering... any camera that's able to meter in Live view must have metering array in the bottom of the mirror box).
4. With mirrorless cameras.
In other words, the way cameras are designed and used today, a viewfinder eyeport shade or cover is rarely necessary. I think the manufacturers supply the cheap little rubber covers that slip onto the strap just to humor "old school" users who think they need them... and for the occasionally user who makes really long exposures in bright light... or for the three remaining individuals in the world who make self portraits with their DSLRs, instead of with their phone and a selfie-stick!
Besides... if you really want one, YOU have an eyeport shade built in. Your thumb works quite well!

Your Canon A1 was an expensive camera. Canon didn't put it on the AE-1. Today the 1DX series still have the blind.

I'll bet if you wrote to Canon and asked them, you'd get an official reason, as opposed to the guesses you'll get here.

Thanks for the pictures. I wasn't sure what this was! I have one on my T6 and never thought about it.

I guessed so. I wrote to Leica asking where do they make the Leica D Lux Typ 109 and they answered me about a month later that they made them in Japan.

And I always thought that little plastic thingy was a hot shoe cover/shutter. I think I will now call my lens cap a lens shutter. (just being silly)

Typical camera today came with both pieces, one for the hot shoe and one for the viewfinder. I was disappointed that the Nikon Df doesn't have the viewfinder shutter although I never use the function.
Well I do use it in only 1 situation but not for taking picture. When I want to test the camera shutter speed in A mode as how long it would be with no light at all. I put the lens cap on but also have to close the viewfinder otherwise the meter does receive a bit of light.
