To be honest, most people don’t give a thought to the OS they use. They haven’t considered the ethics/politics. They’ve probably never even seen a Linux GUI. They bought a device with an OS preinstalled and, so long as it has the apps they want to use : that’s fine. Heck! many of them are still on Vista.
The inertia preventing change (for anything) is enormous (and even more so if you don’t really understand something - like tech) : fundamentally, we’re conservative, and lazy, (and frightened) as a species, and if something works… don’t mess with it.
I am cautiously optimistic for Linux though, because I can see a couple of catalysts for a sea-change.
Firstly Windows11 - which increasingly relies on an internet connection, and a log in. I think this will bar Micro$oft from poorer communities - especially since it requires new hardware. And I think it might make governments and businesses wonder what information Micro$oft are mining.
Secondly the tech trade war - China is one of the biggest producers, if not the biggest producer of electronics, and they constitute 20% of the market too… And they’re moving away from US proprietary systems : The electronics which are going to be coming out of China are going to have an Open Source OS.
Another vote for SearX from me.
