How bad is Zoom with E2EE enabled?

Questions

I would always choose to use Signal over Zoom when I have a choice. However, I’m involved in a group that is going to be using Zoom for its meetings. I don’t think that I’m going to be able to convince them to use Signal, but I think that I will be able to convince them to enable E2EE in Zoom. How bad is this for privacy?

It seems to me that with E2EE enabled, Zoom will still get all of the metadata (e.g. who’s joined the meeting remotely). I have a Zoom account that I created a while ago with an anonymous email account. I almost never use it, so hopefully Zoom won’t know that it’s me.

I already send emails to other people in this group. Although I use ProtonMail, most of them use GMail so Google already knows that I communicate with these people and has all of these email conversations. This seems much worse to me than joining a Zoom call with E2EE. I feel like I’m not giving up much more privacy with the Zoom calls than I’ve already given up with emails.

…but maybe I’m missing something. Please let me know.

If it’s E2EE then you should be fine. Apparently they offer post-quantum encryption on some of their clients so you can maybe look and make sure everyone meets those requirements. But yeah I think for video calls, PQ E2EE is about as good as you’re going to get anywhere else.

What about metadata protections here?

I can’t find anything about them explicitly protecting metadata so I think it’s safe to assume they’ll know which accounts are talking to each other and when etc. But the content of your convos will be safe.
