Oh, I understand that very well, I just live not in a bubble, where I think that everything is fine, as long as it is small enough.
And this is excactly the reason, why we do have so many problems in the world.
The people live only in their own universe, get only the informations from other people with alike opinions and knowledge, or be the victims of a few people who have the power to influence all other within their bubble.
The Religions you mentioned are a very good example for those structures, as there are the members, who are often “kept” within their community, and hear the pastor, priest, imam or whoever is standing in front, and telling everybody else, how they should behave and react.
A lot of people at the moment are rushing towards Mastodon, because they hope to get a kind of replacement for Twitter.
But Twitter, with all its problems and downsides, gave at least a chance to have a look outside those communities and bubbles, if people were looking a little bit around.
If Mastodon does not “allow” this, because the Admin of the single server are defining the “content of the World” then it is for sure not something that could replace a service like Twitter, and help spreading knowledge and (true!) Informations in the world, by letting people decide by their own, if they want to have a look onto the view of “the other side”, or a different opinion or way of life.
To keep (or transfer it into one!) the world a save place, we need a way to communicate and getting informations, outside our own narrow communities, to build an understanding of the other, and to enhance the education of the today very often poor educated populations of a lot of countries, which open the doors wide for the spreading of “Fake news” hate and pure lies, with the goal of establishing or ensuring the power of a group of only a few people over their communities or countries/regions.
I don´t know, if for example Poland and Hungary will agree with you on that…
As long, as not everybody in a community (independent if there are 10 or 10 Mio. “Members”) agrees to a set of “universal rules”, it will not work over a period of time.
It does not matter, if a country like Hungary starts an Authocratiy within the EU, or a state like Texas or Arizona is “trowing the Federal out”.
Neither the EU, nor the US would survive a behavior like this, and this is the same with a social network like Twitter or Mastodon (if this will become a global player).
The “real” problems (everything before that were only some glitches) on Twitter startet within the last two weeks, as a company led by a group of people who grew into their positions, was suddenly led only by one person, who has an autocratic Management “approach”, and little knowledge how to run a business like that.
