Summary: The "something" Foundation (something they make money from, without even using it, supporting it, let alone understanding it) is outsourcing almost everything to Microsoft (GitHub, proprietary software). It's just constantly milking the trademark of Linus Torvalds to make a lot of money and now it uses Apple and proprietary software to prepare a report about Linux (maybe Linux Foundation is the wrong name for it).
Given Mozilla's utterly rubbish marketing these days (politics over technical aspects), set aside the cheerleading for slop, there's hardly a chance of Mozilla Firefox reaching or exceeding 10% again
"before that, every distro that wanted to respect its users' freedom had to remove itself all of the binary blobs that were distributed as part of the kernel Linux's so-called sources"
