Yes, I know it's more comfortable that way, but if you have to decide between giving all your data from all your meetings to a random US company and a slight annoyance whenever you do conferences with more than 500(!) participants, the choice is pretty simple to me.
Giving all the data to zoom probably means also giving it to most US law enforcement agencies (should they request it), that would be a big no no for me.
