A provider having more than 50 users and offering more than one service doesn’t make them evil. Use Proton. They are the best, and they’re not likely to disappear. If you intentionally seek out small services because you think being an underdog is some sort of privacy merit badge, you’ll get “absolutely fucked” over and over again.
Also, you should consider paying for the products you use to encourage sane and user-friendly business models. But that’s a different discussion altogether.
You are not wrong, but there is a reason that identification requirements exist for domain registration. In any case, however, at the end of the day a person who registers a domain through Njalla does not have ownership of the domain. This is not an insignificant fact no matter how you spin it. It’s not your domain. You’re blindly trusting someone whose credentials are to have pirated movies two decades ago with something that might potentially be tremendously valuable, if to no one else but yourself.
Unless you’re literally doing something illegal, choosing Njalla over a regular vendor offering WHOIS privacy is to move beyond privacy consciousness into the realm of paranoid recklessness.
I’m not sure I understand your problem. Installing demos in Steam works exactly like installing any other game in Steam. Click the install button, and then launch the demo. What’s causing you trouble?
The part about the SD card I don’t understand either. Are you trying to access your Windows installation from your Steam Deck? What are you “testing”? Whether you like the game? Or whether it works on Linux?
I think you need to read up on the reasons why services like GMail and Facebook are free.
