No not all Debrid services are under the same jurisdiction. The reason this has been a topic lately is because most of these services have been hoisted out of France specifically. And the French are extremely strict when it comes to copyright and DMCA, to the extent that they actively hunt down the individuals hosting such services through their social media. One fine example of this here. .
So essentially just need to stay away from countries hosting their services through France as it’s more likely to get shut down.
I was in your exact same boat a year ago, and decided to try both solutions. I ended going with the streamlined one. As you said, you are already paying for the service and Proton Pass is imo a pleasantly nice password manager to use. It is a lot easier to create and delete aliases there than through Bitwarden/DDG, at least that was my experience. Proton pass is now my most used day to day app list and I’m very happy with it.
While all eggs in one basket isn’t great from a security stand point, I am pretty happy with this solution. I do however keep 2fa in separate app, Ente Auth.
