I'm running into more and more programs, like web browsers, that require macOS 11 (Big Sur) or higher. That was the first macOS to support ARM processors, so the implication is that if you're a Mac user and not running Apple Slicon, Apple wants you to buy a new computer. And since there's such a push to force encourage people to buy a new computer, there's not much incentive for companies to update older software for an ever-diminishing user base.
Do I like that? No, nor do I like that Apple promised FireWire devices could always work with Thunderbolt adapters. But if the OS doesn't support FireWire, it doesn't matter if the hardware does.
With music industry companies like Line 6, if Apple or Microsoft sneezes, Line 6 catches a cold. Remember all those emails from companies a few months back, urging users not to update yet to the latest macOS because the companies needed to test and patch their plugins? It happens a lot, and that's time not spent on developing new products, providing support, or giving their employees raises. Just sayin.' /rant
