Those are like the most superficial layer of propaganda. The real danger of propaganda is that it doesn’t look like it, it looks like other regular people making you support their interests without you realizing it.
Do you like engines? Do you dislike electric vehicles? Do you like guns? If so, when and where did those ideas come from? You weren’t born with them.
OTOH, it’s understandable given the endless apettite tech has for profiling people. The Fediverse is not Big Tech, but Big Tech wants all the data anyway, and given its open nature, it will get it eventually. Temporary accounts are a way to make it a bit harder for Big Tech, at the cost of making it worse for legitimate users.
If the Fediverse had some protection against data greed, maybe less people would be wary of leaving a long data trail. The best it can do so far is using nicknames and multiple accounts.
