On the one hand, anything that acknowledges Android as being a Linux system is welcome.
On the other hand... ugh, user-agent strings.
I don't think the ffmpeg maintainer is complaining that Microsoft is using ffmpeg, rather that they are opening "high priority" bug reports based on customer complaints. This might be a high priority problem for Microsoft but that does not make it so for ffmpeg.
The license allows Microsoft to use ffmpeg but they aren't entitled to demand free labor from the project. Really, no one is entitled to do so, but Microsoft being a large company who can definitely afford to put money or talent on the problem makes it only that much more egregious.
edit: I would note that asking for help or reporting a bug is usually welcome, the problematic part is demanding help because it's a high priority issue for YOUR customers.
Unfortunately a lot of this seems in reponse to Midori, a seemingly hostile fork with a pretty suspcious website.
To some people all forks are hostile. This appears to be such a case. He just seems to be sour over people exercising the same freedoms he got from Mozilla upstream. Rules for thee but not for me. The free software community doesn't need his obscure fork.
Discord is a proprietary centralized service that is hostile to privacy and third-party clients.
Google is also one of the most prolific contributors to Linux, and was the #3 corporate contributor in 2022. If you're avoiding everything Google had a hand in you literally can't use any GNU/Linux.
ChromeOS is Linux with Google’s desktop environment
Always has been. One does not "use Linux" they use an operating system built on top of Linux.
Chrome is not Linux, but Xfce also is not Linux. Gnome is not Linux. KDE is not Linux. Linux is Linux.
Software freedom applies only to hardware you personally own. It wouldn't even apply to machines you interact with but do not own (such as ATMs or kiosks) since you aren't the one who agrees to the proprietary software license.
Stallman himself explains it in his computing FAQ.
We live in a timeline where desktop apps all run in a browser, whereas mobile websites are all their own apps.
I'd just like to interject for moment. What you're refering to as Linux, is in fact, Steam/Linux, or as I've recently taken to calling it, Steam plus Linux. Linux is not an operating system unto itself, but rather another component of a fully functioning Steam system made useful by Steam Proton, DXVK, and vital Wine components comprising a full OS as defined by Valve.
I say this as someone who is probably one of the biggest supporters of software-freedom around here, but bullying or shaming people for preferring non-free apps does nothing but incite resentment towards the movement. I value the four freedoms because I think I deserve control of my computing, not because I think it's my place to dictate what others should value.
Translation: "no"
Notice they avoid using the exact term "open source" in this press release. I'm ~90% sure it'll turn out to be under some proprietary source-available license.
