The open-source community doesn't like Microsoft because Microsoft is hostile to open-source. It's their MO to embrace things first and people with short memories laud them for it every time. It's very disingenuous to quote their hostility as one of the problems when really it's a logical historical development. They're going to have to put in a lot more effort to make amends for all the terrible things they've done over the years.

But all of that is really beside the point. Saying the "community" needs to fix it means they won't put time or effort into doing it themselves, which by extension means the integration will most likely never be as good as what they have prioritised. This will relegate their "cross-platform" solution to the realm of all the other frameworks: Bad.
