Although there are a ton of alternatives out there they are all "too hard" or something, so since Zoom mostly works OK most of the time and is dead simple to use it will continue to win out over everything else.
My position on Zoom hasn't changed since 2020: Anyone using Zoom will continue to get exactly what they deserve.
Users vote with their feet based on cost and UX. While intertia is certainly a thing, there's a reason Zoom got a foothold while others didn't. The ability to send out links and having people join the meeting without creating accounts or manually installing clients first is huge in most real-world scenarios. Could you do that with... Teams? Skype? Hangouts if they weren't gmail users? Do those people know anyone with the knowledge and gumption to host something?
From the beginning of my involvement in FOSS like 25 years ago, developers have griped about non-technical users being intimidated, or even just really annoyed by UX resistance that we consider trivial. That's the primary reasons open source alternatives are alternatives rather than the standard in user-facing software.
this is how it used to be, until HTTPS and cloudflare-like hosting solutions, were guzzled back like electric kool-aid. all you really needed was an IP and perhaps a port number if endpoint was behind NAT.
