I dunno--I'm just not seeing this as anything unusual. A frustration, yes, absolutely, but nothing specific to the Sims that doesn't exist in a bunch of other places. Technology gets updated so fast; computers have shorter and shorter functional lifespans.
I'm an avid Pokemon Go player, and the phone I started playing the game on can't play it anymore due to one of their AR updates. (Hasn't been able to for months, actually.) They could have just disabled the new-and-improved AR in older phones, since it wasn't essential to gameplay, but nope. They made the whole game nonfunctional. The game only came out in late 2016, and my original device is already outdated.
I'm a Mac person, so when I looked up the requirements, it turns out any Macs made after 2012 should be fine. That's 7 years ago. It's really not that strange to say that a 7-year-old machine can't handle the game anymore. (PCs might be a different story--no idea.)
Again, you can argue that the whole rate at which we have to replace our technology is ridiculously fast and stupid and ultimately unsustainable, but that's a larger problem, not an EA-specific one.
