The problem is those companies (premiumize, debrid, whatever) are entities that make profits from filesharing and give nothing back to artists. That’s not morally defensible.

Filesharing itself is perfectly morally defensible, and in fact sharing culture is good for society (including artists).

So while they might be convenient, they also shouldn’t exist in the first place. Parasitic companies shouldn’t be rewarded for their patristic behaviour.
