I think also the UI is complex because of all the different use cases Zoom can be used for. I work for a Deaf school where it is not uncommon for >50% (if not 100%) of participants in a meeting to use sign language. While Zoom is not perfect for this use case (it has many defaults which assume people want audio) it offers many features which makes it easier to manage meetings. The most complex meetings we have are when there is mixed-mode (e.g. some people speaking and some people signing) where we have someone speaking and the video spotlighed onto a interpreter OR video spotlighted on to a person signing but with audio coming from the interpreter voicing for the signing person. This is a specialised use case I accept, but one Zoom handles out of the box really well. As a result the Deaf community have taken on Zoom for pretty much everything--from professional meeting all the way through to using Zoom for home catch ups with friends/family. Hangouts for some reason doesn't really do this very well--and in addition to the poor video quality (making it hard to see people signing) the Deaf community have pretty much sidelined Hangouts and other products.
