I don't think EVERYONE needs to understand / know about it. I mean, I remember when I was young most people had no idea how to use the internet (hell, they didn't even know how to program a VHS), yet I was perfectly happy using that technology.
I only need a specific set of people and specific communities to be there for it to be worth it. Like I said: I no longer use reddit, even though the fediverse has only a small fraction of the content existing in reddit... I would have expected people in the fediverse would be more receptive to unpopular but technologically/ethically superior alternatives.
Wouldn't it be easier and more direct to simply impose a tax to those external big tech services?
I don't understand why using protection against "bad actors" as an excuse is necessary at all if getting money from big tech were the ultimate goal. A lot of people within the EU would happily support such a tax targeting big US companies, it's the privacy problems what we are pushing against, not the fees. So I'd expect a more direct and honest fee for external companies making business within the EU would be easier to pass if that were what they actually wanted, wouldn't it?
