Very few users care about how much RAM their media player uses. The practical difference between 370MB and 100MB is basically nil for any normal workload. It affects nothing but how many unlikely-to-be-used files fit in the page cache.
Considering the way Microsoft's product line is these days, I have a hard time believing its terabytes of "telemetry" go anywhere but the Windows equivalent of /dev/null.
I expect there's someone out there who tiles 10 instances of simultaneously playing audio/visual media, but that's not most of us.
Given that 8GB machines are still widely in use (and will get even more common over the next years), 250MB of extra RAM use is a pretty huge portion of user's available RAM pool, so this is quite a big change.
Famous last words.
The price of RAM skyrocketed in the last months. The users will care.
