Summary: The Linux Foundation is gradually becoming a shadow of Microsoft, just like the Open Source Initiative, where most of the money comes from Microsoft and the official blog promotes Microsoft, its proprietary software, and Microsoft’s side in a class action lawsuit over GPL violations (with 9 billion dollars in damages at stake).
They have a revenue of 139 million in 2021, so they have some relevance, but yeah i would try not to put too much trust in them, and try to put in funding to the linux ecosystem that is “cleaner”.
