Some 10 years ago I was a Mozilla volunteer. I mainly worked on MDN, to the point of becoming a so-called "topic driver" for the glossary. Some of the work I did landed in the citations of a couple of papers about web technology. They flew me a whole week to Vancouver for an event where employees and volunteers worked together in the same room and they even made me (and the other volunteers ) attend a sort-of-corporate meeting where they sort-of fought about something (can't even remember what it was).
I'm telling you this to highlight that volunteers where a huge part of Mozilla.
But on the last day they announced that they were moving the day-to-day conversations from IRC (an open protocol) to Yahoo Messenger (a closed protocol). I felt sort of betrayed in that moment: the company that was all about openness and to which I dedicated countless hours doing unpaid work for and even more years evangelizing for was imposing its volunteers and employees used a proprietary app to coordinate. That didn't sit well with me. At all. I basically lost interest.
This was in 2015. Last I heard MDN introduced ads (I wouldn't know, uBlock is pretty effective) and is not showing contributors to a page on the page itself anymore.
So yeah, the part of OP saying how Mozilla managed to piss volunteers resonated pretty hard with me.
