Time to learn more on DPI, thanks.

If you want to explore and make some tests of your own, nDPI is the most popular open-source DPI engine.

Hi, I was wondering how is it technically possible for Russia firewalls to block calls over these platforms, while keeping chat messages working? Thanks

My guess is that it is because of a different layer 7 protocol than HTTP is used for calls, and the code of the protocol leaks in the TLS/SSL header. Is this guess correct?

Does it have some other "actual" featuges compared to OrganicMaps?

Sure! Check here https://news.ycombinator.com/item?id=44455300

No “Donate!” buttons at all.

I just installed comaps from f-droid and see exactly the same amount of donate buttons - one.

It's Královec in Czech.

Good to know, thanks. It’s reasonable to expect language-specific names, just strange to see it in English (even in German that is a bit weird).

Koenigsberg is a somewhat known name due to Euler's bridges problem. Kant also lived there.

I have seen his grave there :) It was renamed long time ago and the name is not contested neither by Germans nor by Russians (it’s not liked either, but the government abandoned the idea of renaming it back for symbolic reasons — it’s not about commemoration of Kalinin at all, nobody remembers him). Among Russians Koenig is indeed used as informal name akin to Piter (St.Petersburg) or Ekat (Ekaterinburg).

It's more like a running joke by now, giving Královec 'back' to the Czech Republic means they could finally have a proper overseas harbor and a Navy. Just think of the possibilities :)

Also, did you notice Merkur?
