Right now zoom is going through a honeymoon phase. Only us geeks care about its security and privacy. After this is over though, people will start thinking it through and things will look a lot more like how FaceBook is viewed right now...
I'll happily trade my privacy for a video call that works properly. None of the various Zoom issues have been privacy problems that I really care about.
I dunno. My boss is an incredibly tech savvy developer and he loves Zoom and thinks it's fantastic so I don't really see it going anywhere for a while.
