I use Stickers and Gifs quite extensively and a lot of ppl i know do this too.
And from the idk 5 or so clients i used only one has a solution that works good, but it had a super high frustration hurdle.
ppl just do not care about E2E, they care if their emotion they have can be easily represented and how much fun it makes to write with friends ... all Matrix clients fail miserably at this.
@m @rysiek True. Also the clients are sometimes horribly laggy and slow (looking at you iOS Element...) These days user-experience needs to be good, otherwise you can't really migrate anyone but your hardcore-nerd-friends over.
