No biggie but I have gripes with Sony's failed proprietary approach: betamax, mini-disc, memory stick, DAT, ATRAC, and universal discs come to mind...
Don't get me wrong, some of their products are way ahead of its time and the thought process to create them is astounding. I will not argue that LDAC is great or the 4.5mm connector is solid. It's how they decide to market them that makes me mad.
Seems only with mega market share can one use a proprietary approach. Then everyone reverse engineers accessories at reasonable prices and everyone is happy. Otherwise people are pissed off. Sony is almost there with camera gear, but still their proprietary lens mount has limited lens availability (and thus pro adoption). All pros seem to shoot Nikon or Canon.
The Sony proprietary lens mount is just an updated version of the Minolta system they now own.
Sony bought the SLR division of Konica Minolta in 2006, and thus gained the basis for their Alpha series of cameras. (Ref: https://en.wikipedia.org/wiki/Konica_Minolta )
Before that, Sony was already making point-n-shoot cameras.
If you want to shoot low-light 4K video, the newer Sony Alpha cameras are really amazing.
But, you're correct in saying that there are not as many system, or 3rd party, lenses available for the Sony cameras.
