Not necessarily. If they’re low on cash then cutting unnecessary costs is not unreasonable. What is Mozilla’s core goal? Perhaps the “advocacy” and “global programs” divisions weren’t all that relevant to it, and so their funding is better put elsewhere.
I’ve found my participation slowly declining here on the Fediverse, and ramping back up again on Reddit. I think I’m never going to stop coming here entirely, there’s plenty of neat links that come along to explore, but the main thing that’s causing decline is that IMO the communities here are a lot “bubblier.” It’s probably inherent in the simple fact that they’re small, and that they’re populated by a very self-selected fragment of social media, but the result is that if I “say the wrong thing” I get pummeled with downvotes and snide comments a lot easier here. Makes it less interesting to comment at all. Some of Reddit’s communities are pretty insular too but at least there are enough of them that I can find ones to my taste.
As a major example that comes to mind, all of the technology communities I’ve found here seem to be quite strongly anti-AI. I have an interest in AI, but when I click through to the comments on stories about AI topics it’s often nothing but rants about how awful it is. And if I say anything - even to correct a factual error - I get piled on. So lately I just sigh and move on.
