Plus side: apparently Zoom provides an Ubuntu client (I'll have to see whether it works). That is not to be underemphasized. Down side: Why do folks have to choose between forgoing opportunities and installing proprietary software when there's perfectly good open-source videochat software available? And why do developers like Zoom assume that all Linux setups are x86 when Ubuntu and much of its software ecosystem work just fine on ARM? We've got to beat the drums, spread the word that we exist.
