One of the problems is that a “privacy-respecting solution” that includes a monthly bill is self-defeating. It creates a paper trail.
I told that in the most general sense. You may self-host or rent a VPS, all cost money and maintenance. There is always more private and less private options. But anything run but a volunteer or community or selfhoster wouldn’t data mine to sell ads, that you can be sure.



First step is to figure out if you have hard requirements i.e. specific software that you rely on your studies or work and cannot be replaced.
If there is no such requirements, or your requirements have Linux versions, best thing to do is do the jump and accept the struggle until you figure out the new way of working. A lot of games run fantastic. Heroic Launcher for GoG and Epic games, Steam for Steam.
You need to edit a video, just search for “Linux video editor”, same for whatever task you want to achieve.
