I don’t see how them two things are related, my email has nothing to do with my chattings. it also doesn’t explain why it’s needed as it supposedly acts like a aggregator for the different protocols. upon signing up with a throwaway, it reveals itself as a matrix client and all them chat bridges are hosted by them. I have no idea as to their reputability, credibility, and longevity and at this point this is way too many things I need to get to the bottom of in order to consider it, so I’ll check back in a year or two and see how it’s holding up.
