I don’t think it’s the best approach to promote Element specifically, but rather Matrix.org, which does have good mobile clients, like Fluffychat on iOS, and good desktop clients, like Mirage.
"A faster response"? Is this a satire? Matrix is the slowest chat network ever. 500ms is considered a good latency on the Matrix network! The Element client is the worst and unusable (because of latency) over Tor. I love what matrix is doing with P2P (among other) but "faster" is definitely not their selling point ;) ;)
