It maybe comes from an all or nothing mentality. I would have tremendous Schadenfreude if Reddit does indeed die, but the culture there changed and I don’t really care if all of Reddit migrated here. As long as Lemmy is active enough, I am content.
I agree with what you say as one aspect of it. But there could be insidious uses of your data. What if your insurance company pays a couple of raccoons to sort through your trash and find out you eat fatty burgers and fries for most meals? When the raccoons get back with that report, what is to prevent your insurance company from raising your premium since you are at risk (according to them) of a heart attack?
I’ll probably end up spinning up a virtual machine just for Youtube if they decide to go after Invidious and Freetube.
Most of the Paradox games support Linux natively. I play Europa Universalis 4, Stellaris, Crusader Kings 2 (haven’t bought 3 yet but it has native support), Hearts of Iron 4. Victoria 2 doesn’t have native support and I didn’t get Vic 3 but it is supported. Rimworld is native, so is Factorio.
Have a look at what you want to play on protondb.com and figure out if gaming on Linux works for you. Baldur’s Gate 3 has a gold rating (gold being one level lower than platinum - the best rating for non-native games) which for all practical purposes should work.
EDIT: I recommend installing Proton Glorious Eggroll in addition to the native Proton on Steam if you can’t get a game running with the native Proton despite protondb reports saying the game works. The installation is fairly straightforward, just read and follow the installation instructions on the page.
