The "Backwards compatibility" issue is an interesting one. For years, companies like Adobe used OSX upgrades as an excuse to force paid upgrades. Hardware manufactures did (still do?) this with Windows drivers. The other side is that Apple deprecated 32bit support around 2011, dropping it in 2019/20. They've also introduced and deprecated a few frameworks in this time. They have always announced well ahead of time. People get caught short by not paying attention. With regards to OS upgrades, there has always been a vocal minority that likes to complain, ever since the System 7 days, sometimes not without reason but it's minor. Overall, the upgrades are decent, but I'll agree it's not always plain sailing for everyone. The thing with macOS is last year's Lemon is next year's gold. Rose tinted glasses are abundant online, especially with competing OSs.
