I think there is a danger, but hubris has gotten them way up shits creek & their relevance was rapidly moving to 0. Desktop platform is dying, mobile barely matters and they have no presence there... Microsoft started playing with others because pretending they were the unilateral giant that could dictate terms to the world landed them on a small shrinking pathetic island. So help them gods if they try that shit again.

That said, I 100% absolutely endorse caution. The past couple years of behaviors are no indicator Microsoft will stay a societally-positive technological force. The corruption & darkness & manipulation could play back in at any moment. Already, Microsoft creating very special terms of service for things like VSCode Remote Development Plugin, having extremely fantastically proprietary implementations for the incredibly useful/popular/fantastic LiveShare are harbingers of the old ways, indicators that Microsoft just wants to force the door open, not really engage & participate.

For now though, I still overall think they are doing good work, pariticpating/not domineering (with some caveats). They learned very very very personally what happens when you violate the core rule of software, the most important maxim, not couched as such but absolutely of key vitality to computing: "Create more value than you capture." -Tim O'Reilly. Of course, all organizations forget the/their past. And I quake thinking of how many people pretend they are using/learning Linux while never seeing systemd, freedesktop, the greater Linux project: WSL is amazing but a dark & tragic small death for the real open source, & it's cheered on & fanboyed endlessly for enabling the blessed ignorant. You are right. Adopter beware.
