Yeah, with the recent issues they had after doing the cryptocurrency stuff (which didn't really bother me, but it definitely seemed to generate some negative feelings in general), this feels like a poorly-timed move.

Zoom is presumably going for "look, we are bringing on-board this team of trusted people who understand privacy", but I think most are just going to assume it'll work the other way and Zoom's culture of poor security practice will bleed into Keybase over time.
