> Why should Fastmail invest in Thunderbird, an open-source email client run by a completely unrelated organization?
One very good reason is that Fastmail created the JMAP protocol and while work on getting it into Thunderbird started several years ago, it hasn’t progressed. So JMAP is kinda stuck (obviously Microsoft is not going to put it in Outlook).
It could’ve been a win-win-win for JMAP, Fastmail and Thunderbird to accelerate the implementation and support for JMAP within Thunderbird. This would/could help in JMAP adoption by other mail providers too.
