I never claimed that 2^20 is the same as 10^6. In fact, I explicitly said that they are different. But if I use M on purpose, it is not a correction to just replace it with Mi, for that same reason.

There is no contradiction. But there is also nothing contradictory or wrong with the unit MB. If I say "this is 100MB", maybe I just... mean that? No reason to correct me.
No. "Mi" is just a different prefix than "M" and it doesn't matter what units you attach them to. Why would it? It's just a multiplication with 2^20 or 10^6, respectively.
The more important thing: anyone can see their posts now. This is rather crucial for a government institution's feed and not true on Twitter anymore.
RE: Copyleft
The idea of copyleft is that you give anyone the freedom to do anything with your work, with one essential restriction: they do the same for their changes, derivative works etc. Technically attribution doesn't have to be part of a copyleft licence, but all copyleft licences I know have a requirement to preserve copyright info.
And yes, it is popular in software (GPL, MPL, EPL), but for other types of works there is CC BY-SA 4.0 (Creative Commons Attribution-ShareAlike). If you want to copyleft books, images, videos, other forms of text... this is the way to go, IMO.
Some additional remarks, just to clarify:
- Copyleft is not "giving up all copyright" - copyleft essentially "plays" the copyright system in a way that makes sure nobody is restricting access to or usage of one's work. Using the rules of copyright against copyright, if you will.
- In some jurisdictions, there is no such thing as "giving up all copyright" or "dedicating something to the public domain". Best you can do, generally, is giving users all the same/relevant rights.
- Most Creative Commons licences are not copyleft, only the ones with a ShareAlike (SA) clause. Some CC licences are also nonfree, meaning they don't give you all the freedoms to do what you want with the work. The 2 possible nonfree clauses in CC licences are ND (no derivative works) and NC (no commercial use). NC can also be used together with a SA clause, making CC BY-SA (free) and CC BY-NC-SA (nonfree) the two CC copyleft licences.
I love German regional trains. This is a very common issue. Happens all the time.
The new one is definitely too expensive for me. I have a phone that I'm not really happy with, but I'm keeping it for as long as possible. After that, I'm probably going to look for a used fairphone. I don't see myself going with another completely unrepairable device.
