It was funny (and untrue) when desktop Linux was constantly at ~1% market share. But now with desktop Linux slowly but constantly rising, it’s actually true!
They probably reached their goal. It was never about efficiency. That was just the PR spin to sell it to the public. It was about getting rid of pesky regulatory bodies which stood in the way of making more money. Especially those who hindered Musk’s companies.
The USA is currently experiencing the end phase of capitalism: massive corruption turning into open corruption with an economic oligarch class fusing with the government, massive income gaps and problems for regular citizens, class and culture wars plus reappearance of fascism to keep the population busy with culture wars among themselves instead of uniting against the exploiters, and so on. But it just started in USA. It’s already swapping over to other western democratic countries as well.
You becoming a neo-nazi by constantly being served right-wing propaganda on company-controlled social media channels is better for their business than if you were a neutral, critical thinker. It’s why Twitter was worth the 40 billion for Musk. Not because he expects it to ever repay itself. But because he can produce more loyalists by influencing what the algorithm shows and hides for you. Nazis are great for them because they’re busy fighting against other parts of the population while giving the wealthy class a free pass to do what they want. Which is more money, more influence, more exploitation.
I was a bit disappointed with desktop Linux during the late 90s and early 00s because many applications within the typical ecosystem weren’t great or mature yet (I still shudder when thinking about the amount of time I spent trying to get audio to work nicely across OSS, alsa, artsd, esound, … this was before pulseaudio or pipewire, obviously), and then I temporarily switched back to Windows as a primary OS just because of gaming compatibility. But since the mid-10s or so, Linux grew to become very capable for at least casual gaming as well. So there was no need for Windows anymore and I just wiped it off of every device, leaving Linux as the only OS. This was also during a time where Windows 8, 8.1, 10 and later 11 showed up and this really showed to me that Windows was doomed to die a long-winded death. The last decent version of Windows was 7.
