I've used Discord for a long time and my previous startup was even part of the Hypesquad program. However, I'm really concerned with their views around E2E encryption. We've asked many times for an end-to-end encryption service. This became the #3 most upvoted request (https://support.discordapp.com/hc/en-us/community/posts/3600...). Unfortunately, their "rejection" and user comments were deleted after they switched feature request systems.
It was something along the lines of "we take security seriously but we won't do this." IMO, it's pretty important for them to actually consider implementing this.
