More people have to suffer usually if software ends up long lived without being pushed to upgrade when there are newer technologies that improve the experience - it's a heavy price of others you're asking for a lot of times when choices have to be made between compatibility and improvements that often get discounted unreasonably.
I look at all of the Mac software I've lost and will lose to upgrades over the years, including the offline-only parts of my workflow that held back only myself, and weigh them against this bright new future of low-effort blown-up tablet apps on my desktop that they were sacrificed for. A heavy price certainly has been paid here.
Real world is not the web cocoon, even there, switching front-end every 2 years is not acceptable.
disclamer: I know that for a fact as I'm in the process of replacing a CNC control system with modern parts, trust me it's HARD.
It's crazy that we can't run old software on vastly more powerful hardware. Imagine if we suddenly couldn't read old books.
Computers are made up of many small parts the same with software, every component comes from different vendors and they are all working asynchrously to each other and adjusting to the changes around them every time they update or make a new component.
Each new change looks like a tiny leap-frogging, but if you don't update or rearchitechture for a long while it becomes an insurmountable to task to update because the whole world has moved away from under you. Not by monumental breaking changes but by thousands small changes that has added up.
