Stripping the oldest leaves actually has some data supporting it as pot leaves show a distinct decline in photosynthesis as they age.  So theoretically pulling the oldest leaves to allow more light to hit younger ones should have a net carbon gain.  Although as soon as your stripping plants to the point soil is getting hit by light you’ve crossed the line and would be reducing sugar production as any photons hitting the ground aren’t being turned into sugar.

Then of course the airflow benefit like you said, some leaf pruning makes sense but the bro science can easily confuse people as the benefit doesn’t come from the buds getting more light, it’s all about maximising the photosynthesis rate which starts by having a full canopy.
