Five years after Xbox.
There's no need to attempt to diminish what Sony is doing. Anything that improves the quality of life for people that have been previously excluded should be applauded. Even if they took longer than others.
I applaud Nintendo for doing this for the NES, but where are they today?
Because it's not an example of Nintendo being good, it's an example of why this reductive argument is meaningless.
There have been many community controllers but I believe MS was the first to try to make a real consumer product that serves disabilities without DIY stuff. Kind of an odd stunt and a tiny market, but it appears to have made some splashes.
Sure we can 'just be happy', but we can also acknowledge that Sony didn't care about it until Microsoft did something about it. Same as they didn't care about motion controls until Nintendo busted out the Wii. Both MS and Sony scrambled to put out motion shit the next few years.
