The quality of Microsoft's own documentation has also fallen considerably; the latest nail in the coffin is that docs.microsoft.com thing that started to replace MSDN several years ago, that created tons of ridiculous fuckups in the "migration process". While doing that they also "open sourced" their documentation on GitHub, which to me sounds more like they're just trying to rely on free labour from the "community" to fix the mess.

One of the more memorable WTFs I've seen is this, which is still wrong as of this post:

https://docs.microsoft.com/en-us/windows/win32/api/wininet/n...

Compare to the old version of the page on MSDN:

See what's missing? The newer version is not the correct one... in "migrating" the document to the new site, for a reason that completely defines all rational explanation, the return type of the function declaration became void. There are plenty of pages on the new site with this serious error, and they've remained unfixed for well over a year. People report such problems on their GitHub, and they get fixed --- individually --- as they're reported, but it still boggles the mind how such a blatant and widespread error could go through (and the old, correct, content deleted flippantly) without someone in power shouting "STOP!":
