The way I understand this is that your data is e2e with the mullvad key, meaning Obscura can't see what you're browsing. All it can know is who you are (because of your IP address). Mullvad is the one who sees what you browse (if they were to log) but doesn't know who you are because the traffic comes from Obscura's server. That's the difference between Obscura's VPN and going straight with any other VPN where they can log your IP along with your browsing.

Imo, that extra anonymity and speed loss are not worth the extra expense, but it really depends on your threat model.

Also of note, some providers have data caps. I haven't looked at all providers, merely Nymvpn as I was interested. Turns out they have a 2TB/month cap. Might not be an issue for some, but might be for others.

From what I understand Nymvpn uses 2-hop connection, aka your data goes through two of their servers before reaching its intended destination, versus 1-hop with most other VPNs. It's more private, but you'll sacrifice speed as a result of having to go through at least 2 servers. They even have a 5-hop mode, which I don't know, probably would be slower than tor xD

E2EE usually implies that your connection goes through the company's server(s) before reaching your contact during communication. With Mirotalk, your connection is P2P. You connect directly to your contact. Your video stream never goes through the company's server. And the connection is still encrypted of course.

So yes, your stream is encrypted. Honestly, if it wasn't, no way they'd be in business as encryption is probably the bare minimum nowadays when it comes to any kind of communication.

Give MiroTalk a try. Can be self-hosted and just like Jitsi, no need to install anything, it's all in-browser. Has all the features you're asking for.
