My thoughts exactly. In Europe it’s part of our social welfare

I also pay for it and watch it on my android TV. And I completely agree with you. But for now it’s my main source of TV and I mainly follow channels I subscribe. I don’t listen to music on YT, i do follow some live music channels

I also couldn’t get sddm to work from the KDE settings. I changed the sddm.conf file manually and I’m using the catpuccin theme. The Arch wiki helped (as usual).

Security starts first with you. Most of the attacks are done though social engineering. Email phishing, dodgy webpage logins. Normal password security behaviour should fine for you to use the pc. More importantly, what is the distro you’re using? Maybe consider using Flatpaks for the apps, they tend to offer more restrictions on access to the system. (Installing the torrent app as a Flatpak and only give it permissions to a specific folder) One of things I tend to do is install chromium just to login on my Google apps, Gmail, YT. But I’m more of a non data sharing freak.

I haven’t noticed any issues. But only Plasma would be a DE. Qtile and hyprland are WM, not sure if that makes the difference.
Initially I had doubts if it would work, but so far so good.

Nice work. Why move from plasma to hyprland? Install both and login on the environment you want at any time. I have qtile, plasma and hyprland
