In the long term, alternative platforms need to be built on something different than outrage and “not being the bad company”. In the end, the vast majority of people cares very little about the underlying technology, they just want their content and people to interact with. Mastodon is in decline already, the fediverse shouldn’t be a place where people come to say “wow, [company] sure does suck”, and then go back to that company if they actually need a piece of information or reach a person that does not know or care what an API or federated protocol is, aka 99% of the population.
I think it’s a bit naive to think that what Mozilla is lacking is a good CEO. A CEO cannot magically make Firefox the default on Android or have the most visited website in the world shove it down your throat. A CEO alone also cannot improve webgl or webrtc Performance without sacrificing development time on other things. I can’t think of any major problems Mozilla has that are caused by or could be solved by upper management, they simply don’t have the resources and outreach that google does.
