Conversations compliance test has brought most clients into an acceptable base to where most basic chat/audio/video needs are met, so if you are comparing older legacy clients then the experience will be different. The XEP system means everything is optional & can be pitched by making a spec & seeing who uptakes the idea. It also means the bar to create your own server is absoluetly minimal since everything is an extension which means you could build one in a weekend which is great for those learning to code since the barrier to entry is extremely low if Conversations isn’t the goal.

IDGAF about Apple since you have to have a wad just to publish an application on their proprietary store & the EU didn’t do a good enough job so it’s expensive to open alternative stores like F-Droid while also being antagonistic towards sideloading as well as PWAs (not to mention needing to buy their overpriced hardware to build/release applications). Heck, you can’t even publish a GPL-or-similar-licensed app on their store. This is a giant slap in the face to free/ethical software developers & probably why the clients aren’t in a good state; if you aren’t trying to make money, why would you develop in an ecosystem that is entirely hostile for you to develop in?
