Therefore it is recommended to boil the water so that chlorine dissipates.

I thought chlorine was the reason you don't need to boil...

I've watched this video 2-3 times :P

I don't think this is what they mean. If you read the whole paragraph they also talk about "[...]the data that is not covered by end-to-end encryption"...

It says that they have nothing to give on Secret chats, and then: "To protect the data that is not covered by end-to-end encryption[...]" ... "Thanks to this structure, we can ensure[...]" ... "To this day, we have disclosed 0 bytes of user data to third parties, including governments."

I mean, I would consider phone numbers, IPs, metadata, non-secret chats (I don't know if that's a thing, never used Telegram), to be "user data".

Telegram states at their site that: "To this day, we have disclosed 0 bytes of user data to third parties, including governments."

But according to Spiegel this is false. I don't know German, I read the article using google translate, correct me if I'm wrong.

Here is a quote from the article: "Contrary to what has been publicly stated so far, the operators of the messenger app Telegram have released user data to the Federal Criminal Police Office (BKA) in several cases."

If this is true, the fact that they are lying is very worrying...

Are you Big Brother?

I think 1 and 2 make it harder to see what is what, whereas with 3 and 4 everything is immediately identifiable...
