His ranting style is unhelpful but the underlying point is sound—Apple device owners update the operating software at a dramatically higher rate and frequency than any other significant competitor platform. If there is a contingent of iOS device users “conditioned” to avoid upgrades, it would be impossible to prove this contingent exists statistically.

Frequent vocal complainers on internet forums probably only account for less than 0.01% of their installed base.

JFYI 50% is an adoption achieved in only 23 days after iOS 12 release [1]

"Apple’s latest mobile OS hitting 50 percent adoption across eligible devices in 23 days (via VentureBeat).

For comparison, iOS 11, released on September 19th, 2017, didn’t hit 52 percent adoption until November 6th of that year, taking 48 days, or over twice as long as it took iOS 12 to hit its own 50 percent mark."

So now it is probably higher, though I didn't find any fresh stats.

50% in a couple weeks after the release.

Android was 6% after much much longer.
