The new spez company strategy will work because it has been tried and tested in many dictatorships in human history. The elites and workers (mods) in institutions (subs) critical to the state (company) regularly need to be purged of dissenters (protesters) to signal the strength of the dictator and make a coup (change in leadership) seem impossible. This lets those who are against the current course of the state lose their will to fight and pursue other avenues like flight (why I‘m here). It also gives a feeling of safety to those who don‘t care or support, since they need to see less of us dissenters.
Though, in the long run (and I mean many years), I think it will backfire. People like to read all kinds of comments, even those like mine though they are often cynical/paranoid mess. So without dissenters, it becomes a sludge of sameness that appeals only to the most boring people. Hopefully leading to a growth of decentralised platforms like this that could eventually surpass all corporate social media.
This is a problem that is big now, but I think can also be solved with maturing the technology in the future.
Right now I have multiple accounts for multiple bubbles, but I can easily imagine some app or website that can congregate the content coming from multiple instances and choosing the appropriate account for it to post/view with.
Thus allowing one to access bubbles that have shut each other off in one central place. Unless they do it by completely blocking sign ups in which case they isolate themselves willingly and that is also good in a way to have as an option.
If I can imagine all this as a random system engineer, surely some developers with a passion for this and open source collaboration etc. can too.
