First, its like 99% of people doesnt know and gives zero faks about "hardware acceleration in web browsers" and stuff like that, so yeah, but from other side, everything is perfect without that sh1t, its not like this world is full of retards, who have celeron 100 mhz processors with geforce 9999gtx turbo, that someone must have stuff like that in browsers
Second, windows xp is very old os, there was vista, win 7, win 8 released after it, so people with at least one eye must see, that ms is actively doing everything only for newest os. But windows still gets very long support compared to most linux distributions that i know, like ubuntu, which when released new version, then at the same time it becomes old, because everything in it is old, and with updater you can only gets a few security updates and stuff like that.
