I agree with you sentiment here. That’s why I wrote ‘relative terms’ in my comment.
Since Nadela took over, Microsoft did some open thing which benefited community. So, Microsoft opened somewhat.
During the same time, under Pichai, google went the other way: they focus more on monetization and try to control stuff the apple way. Manifest v3? Google also didn’t do anything really worth mentioning in the last 10y in terms of products. Well, except ‘attention’ article. And even this they didn’t believe in and they cannot deliver a decent product. I just tried google advanced Gemini and it’s, to put it politely, shit. Google also had some positive actions like mainlining a lot of stuff in Linux Kernel to more easily upgrade android.
So, while google is closing down and making mistakes, Microsoft is opening a bit up.
If you look the state from the last year and the state now. Microsoft improved. Google went the other way.
Microsoft doesn’t care about open source, they care about the money Cloud Services using open source bring them. I don’t think google cares as well. For reason read this: https://www.joelonsoftware.com/2002/06/12/strategy-letter-v/
