things like this are shared w/o context

I mean, the only information in that truthorfiction link that wasn’t in the original tweet is that Jack Kimble is not a real representative.
Apart from that, there is no other context. The tweet is exactly as it appears to be, it’s not a reference to anything else.
Either you understand that it’s a joke or not.

Having some rights doesn’t mean it’s not still capitalism

I mean using your real name does not depend on the platform you’re using but more on how you’re using it.
Pretty sure the majority of reddit users do not post under their real name and you could use a pseudonym on facebook if you wanted to.
Zuckerberg isn’t going to check your ID when you sign up.

Your data isn’t really more private on the fediverse, is it?
Everything you post is shared with myriad instances.
You might not end up just handing it to some large tech corp but you also give up any remnant of control over it.

Ja, passt schon
