Yeah, but we've been on this stressful ride before, and we know where it ends.
There were lots of attempts at a closed source proprietary Internet protocol. They have all resoundly failed, after looking unbeatable. Some folks still fondly remember the closed Internet protocols like OLE COM, ActiveX, Flash, Cold Fusion, and SilverLight, but few of us miss them. Okay, I do miss Flash games.
Good touchscreen phone operating systems were a "will this ever be matched?" trade secret at Blackberry and Apple. Now the vast majority of phones run open source Android.
Much earlier, most good-enough C compilers were expensive proprietary closed source products. Now I see very little being compiled on anything other than the free and open source GCC. Even most other programming languages and tools are now FOSS, as well. I can't think of much for development that cracks the top 20 that isn't FOSS. JetBrains IDEs stand out as a lone closed source hold-out.
Open standards always win, in the end.
The desktop computing default is honestly way overdue to switch to FOSS. That's why it's the year of the Linux desktop.
The Fediverse is here to stay, and is all that'll be left in a couple decades. But in the meantime, it's cozy!
