Just pointing out that just cause its owned by a big company doesn't mean it'll last forever.

Also the FOSS community is by in large sus of Microsoft cause of their history practice of embrace, extend, extinguish. Which one would argue they embraced FOSS to gain easy access to their projects, the issues, the code, etc to train their models. Which would be OK if all code it generates has to be GPL to agree with the licenses of the collective pool of training data. Either way that's the topic of debate.

It sounds like you looked into your constraints and github works for you. That's great! And that's what's important.
