I use Hetzner’s Storage Share (which is a nextcloud instance) as my drive and pay around 5€ / mo for 1 TB. Depending on the features you want you could also use their Storage Box which is more like a plain network drive, and cheaper… like 13€ / mo for 5 TB.
I don’t need that powerful hardware… it’s the software side that’s mostly lacking for me (as a software developer :)
Sorry but your examples of the problems are pretty minor and solvable by other means (you can’t do much with my credit card details because they require strong authentication which uses one-time passwords). Also, you conveniently leave out all the problems with cryptocurrency. It’s not like you’re protected in any way. We also do not have any adopted implementation of cryptocurrency that’s not slow and super wasteful of resources. So far they’ve also had the ponzi-scheme problem… first adopters can become very rich but late-comers get crumbs or lose everything.
I use Youtube-shorts block -add-on. It rewrites the url for shorts and shows them as normal videos (because they are). IDK why they had to make a new purposefully shitty player for them.
You should be able to do that, you’d just need to set up and maintain the Nextcloud instance yourself :)
