I gone through a lot of hosting service providers and unfortunetly cannot find a single one that can be used without running nonfree programs, all of them require loading bulky obfuscated JavaScript apps.
I know of Codeberg Pages for static sites for example, but it is not suitable for any business or professional use.
I mean … that’s basically how the internet works today. And even if you don’t “run” proprietary stuff on your end, their service as a whole is still proprietary. So it seems like a pointless battle, IMO.
I would rather ensure to use a browser where I trust its sandbox to properly isolate the shit it has to run inside.
