Interessant. Danke!

hmm ... sorry for being so critical. But where does this qualifiy as a meme? It is more like a "straw man" for politics discussion. That's what you want, right?

Thanks for the answers, @schnurrito@discuss.tchncs.de! Because I access the communities from lemmy.ml, I was not sure if it easily will work with other instaces if I just use the link and subscribe. And I thought there might be a feature - that I miss - which automatically integrates the old and new contents.

And yes, I have seen the "locked" label. Still you could subscribe and read the content. That's what's confusing me. - If I don't subscribe anymore, I will still find old topics by the search, right? So some question still remain, and it would be nice if people could answer what will happen to outdated communities/instances. - I guess they will stay online as long as their host servers are online? So in the future, we might have several communities with the same name, some "dead" some active?

Interesting feature, surely possible. I have seen that on "Threema". Of course, secured by two layers of passwords/-phrases and strict connection procedure.

Well, as for many topics, also "privacy" in detail seems to be very different to many people. Personally I like the "auto-expire" feature in every messager app. But I also know people, who get angry about deleted chats. Because they forgot, what's been said in the past or they want to look up stuff months ago, or ... I else don't know.

Hmm ... are you talking about the original Signal app or the Molly app? Because I don't really understand your news here.

For me, as far as I am aware, Signal has always been synchronising the chat history. The only condition being, that you have connected your device before in the past, which I think is a good privacy feature. (Although, I haven't checked, how far back it goes. Never needed that.) - You don't want any random new device read all our history, or do you?

Definitely a classic is "Solaris" (1972 film) by Andrei Tarkovsky. It has a mix of sci-fi and drama, but I can't tell more without spoiling it. It definitely makes you think ... Also other Tarkovsky films have been praised, like "Stalker" that you mentioned. So maybe check out his filmography?

Edit: Something completely different is "The Mystery of the Third Planet" (1981) by Roman Kachanov. It is an animated sci-fi film for children, but also fun to watch as an adult because of the absurd storyline and humour.

Other films I have in mind, too, but don't remember their exact titles now. Will edit this post, if I recall ... Edit: You might want to have a look at the Wikipedia list differentiating by age and/or genre: https://en.wikipedia.org/wiki/Cinema_of_the_Soviet_Union
