Thoughts on how this will get us towards when libre software privacy&security type people are ready to advise friends to move to Matrix for personal communication?<p>(To be clear, the platform has to be all open source and open standards, actually decentralized, guided by those principles -- not an effectively proprietary play even if nominally open. For example, you should be able to get all the same functionality with Element, Fluffychat, Thunderbird, and other user agents, and with any home server, both now and on an ongoing basis. And the user agent implementation difficulty should become tractable enough, in terms of size&complexity and specification, that one person could write a new one -- not like Web browsers have become, where there's mainly only one, that company has been funding the runner-up, and that company can pretty much dictate 'standards'.)
