I hate the fact that it requires you to install the client for it to work.
The client randomly spikes in cpu usage while running in the background. Multiple times I've also had this issue where I'll try to right click the zoom icon in the system tray and quit zoom, causing it to hang and reach 100% cpu usage on one core.
I also don't like that on clicking on a zoom video call link sometimes the browser to client redirect works but sometimes it doesn't and you need to then go back and click the link again.
For me, Google meet works much better.
Take a look at step 2 here: https://it.umn.edu/services-technologies/how-tos/zoom-join-t...
I can see why salespeople prefer video calls but for technical topics it just doesn't make sense.
My suggestion on Linux at least is to use the web client. Just get the url, do a 's#/j/#/wc/join/#' to it and open it in browser of your choice. You'll need to copy the password manually, sometimes it might require captcha etc, but at least it's somewhat usable.
People love to shit on Skype but even the web version of Skype behaves better than zoom for me. Google meet, Skype, meet.jit.si - I take any of those over zoom.
