I totally agree that video conferencing is disappointingly pushed toward half-assed centralized services, and I'm glad to see that Mozilla is supporting a project to make it more open and decentralized. But I'd like to know, what other projects are they working on? Because personally, I don't think that video conferencing is the big glaring problem.
To me, the big glaring problem is text messaging. And no, I don't mean "text messaging" like mobile text messaging, like SMS. I mean the broader category of SMS, IM, text-base group collaboration (e.g. Slack), email, notifications/alerting, and anything else that includes sending a message consisting of text from point A to point B. SMTP is long overdue for replacement. SMS is old, antiquated, and insecure. RCS seems to be better, but not great. IM has increasingly been pushed toward being a bunch of incompatible proprietary standards e.g. Google Hangouts, Facebook Messenger, WhatsApp, Signal, and Apple iMessage. And then there's the group collaboration, which is a different set of incompatible proprietary standards, e.g. Slack, Teams, Hangouts, and some other things.
And then, when you get a message in one of these apps, if you don't keep them open all the time, you have to set up email notifications to alert you that you have new messages. Or something. And you have automated notifications. Working in IT, there's a whole discipline around funneling alerts, errors, and other notifications into email or APIs and then using something like PagerDuty to sort through them all. The whole system is a mess.
There should be some attempt to create a new standards framework around all of this messaging and alerting. I know, some idiot is going to quote xkcd at me, but we need standards. The internet was built on standards, and it's worked wonderfully. HTTPS, SSL, TLS, HTML, CSS, SMTP, POP3, IMAP, XML, and JSON are all standards. There's no reason to dump on the idea of standards.
And there should at least be a good basic messaging standard with toolsets built around it, so we can have all of our messaging apps talk to each other.
