This sort of dynamic is something I feel the Free Software/Open Source world often misses. Yes, security, openness and ideally freedom are desirable and in some cases essential, but if the software doesn't fundamentally work well at its primary task, for its intended audience, those benefits won't count for a lot.

I think Zoom certainly deserves the criticism that they're getting regarding security. But until the alternatives figure out things on the functionality front, I don't think that's a sufficient reason to kick Zoom to the curb.
