Hey Daniel,
1. Why is NoiseBridge using Slack (Corporate), isn't privacy a concern?
I believe the historical reason is that, circa 2015, the people running Noisebridge's infrastructure were overburdened and people wanted something that would reliably be up.
RocketChat, Riot, and others didn't exist back when Noisebridge started using Slack.
Private conversations are on Slack, and so yes, it'd be great to use something end-to-end encrypted and open source instead.
2. Why is tomorrow's (2020/04/05) NoiseBridge CryptoParty being held via Zoom, when the party itself is about privacy?

> 3. Why not use their open source alternatives?
It is a public event. The way I think about this is: privacy violations occur when information you want to be private to certain individuals is visible to people outside of that group.
Zoom v. others was discussed internally and I encouraged Kinnard to use Zoom for this public event because Jitsi Meet doesn't work very well at all if you either have more than a few people joining, or even 1 person has a slow internet connection, which is especially common in the global south.
More good is being done for the world by making the event accessible to all :-).
If we want people to use FLOSS software then we need to (1) make it work well and (2) financially support the people and organizations making that software so they have the resources they need to make it work well!
