How to reconcile Sunny 16 rule with reciprocal rule for shutter speed for long lens?

Silly question but one that has been bugging me. I understand the Sunny 16 guideline (Example: For bright sun and ISO 100 use f16 at 1/100 second). How does this apply to using a long lens (300mm for example) where the recommended minimum shutter speed would be 1/300 second or faster? Does one compensate with a larger aperture? Use a faster ISO? No need to compensate? What am I not seeing? I have searched for an answer without luck. Thank you.
For each stop of shutter speed increase you just lower the f stop an equal number: For 1/200 use f11 for 1/400 use f8, etc.

By my calculation going from 1/100 to 1/300 is 1.5 stops. Just adjust your aperture or ISO (or both) for a combined 1.5 stops.

http://endoflow.com/exposure/Odball i know, but i think of aperture as the opposite of pizza. An 11 inch pizza is roughly twice as much pizza as an 8 inch pizza, f8 is twice the exposure of f11. I think it is not exact because f numbers are rounded. If you double a pizza order (diameter), 4 inch up to 8 inch, you get 4 times the pizza. If you double an f number you get 1/4 the exposure.
So all you have to remember is the first two f numbers in the sequence 1 and 1.4. Double those to get the next two, and keep doubling up the ladder. Double 1 is 2, double 1.4 is 2.8, double 2 is 4, double 2.8 is 5.6, double 4 is 8, double 5.6 is 11, etc.
ISO and shutter speed are straight, 1/30 Is twice the exposure of 1/60, ISO 100 is twice the 'exposure' of ISO 200.
So if you halve the exposure with one setting you have to double it with another to keep the exposure value equal. Here are some charts

This is the only reliable advice. We used the sunny 16 rule when we did not have light meters. They used to be expensive and considered an extra. The "rule" should be renamed the stupid 16 and kicked into the trash bin of photographic history.
I tend to strongly agree...your phone can be a meter these days...

Laziness, Instant Gratification, Convenience, It's always there, snapshots vs photographs, Instagram, Facebook, Social Media in general, Marketing.
These are the reasons Cell Phone cameras are so popular, not "Sunny 16"

Be nice. I think laziness might be a little over the top. Perhaps you are developing a you vs them mindset. You know like....my way or the highway.

Light meters and - and with digital, instant playback and histograms
.
Imagine your life as a successful photographer. What type of phone are you holding?

My comments are based on personal experience and observation not an adversarial attitude.
Frankly, I often use my phone simply because I am to lazy to get out my kit.
I didn't exclude myself from my comments.
