The last Intel Mac was actually just 3 years ago!

The last 20 years we've only seen Apple enjoying the good times. What they did when the money was gushing in from every angle is not really an indicator of what they'll do in the hard times. We're getting into the hard times now, IAP revenue is plummeting because of competition for payments and a whole bag of things are impacting consumer purchase behavior.

This has resulted in positive outcomes like services have largely gone global this last quarter but it's also resulted in negatives like more ads and service price increases in many countries.

Yes they do offer security updates for what, 7 years? That I consider “kind of ok.” Not great. And yes most Android phones are even worse than that. But OS and application updates? You’re dead to them after 4 or 5 years. AND the whole ecosystem follows suit, so if your Mac is like 6 years old, almost nobody is writing software that works on your system anymore.
