Do you play niche or weird games? Most games I play work as well if not better than windows compared to my gaming friends. The only problems I've had on Linux were because I decided to fuck around with the OS while doing some niche programming shit.
I interact with windows enough (since everyone comes to me for their tech problems) and I don't see a reason that Windows needs to still exist. Ads everywhere, cancerous data collection practices, crappy products that lag or glitch. Its a mess and I hate every time I have to use it any more. Nowhere near the same feature richness of linux, costs money, and they are constantly making poor anticonsumer decisions.
It was to make the data inaccessible to general people, therefore removing the reason people visit reddit. Even if reddit could still get the data, regular people would be inconvenienced (in theory) and look somewhere else.
When I tried self hosting it I kept getting trackers blocked by ublock. From just my self hosted instance I get 0 blocked, but with the materialious frontend it would keep climbing. I killed my instance when I reached 90 blocked. It was ublock in hard mode
Garbage take. Having apps as PWAs is better for security, privacy, and doesn't need to be clunky. Websites are clunky when they import massive remote JS libraries instead of just relying more on CSS. No website I've every visited has had a valid reason to be slow, I mean we can literally use a webpage to control a remote VM in real time. Apps get to declare most of their permissions and will often require these unnecessary permissions to use them at all.
For security, yes, your word is not enough. This would be confidentiality in the CIA triad. I still understand your disappointment seeing probably many dozens of drives get destroyed. I get the majority of drives by scrapping old PC and it pains me to see what people will throw out.
