Founder and CEO of Telegram messaging service arrested in France

But this is intentional. TG's ToS forbids alternative clients with their own E2EE.

Also he's the VK founder, which kills any idea of "trustworthy" immediately.

It's part of TG's business model, I think, something in the price list for governments. And the way they treat alternative clients in reality also hints that maybe backdoors are as well. Say, a new message format of the day (they add them really often) arrives in a new official Telegram version, somehow it's nowhere to be seen in the channels and groupchats you're in, but some day a DM arrives with harmless text and some code runs on your client machine.

I use Telegram, but trusting it would be asinine. Even trustworthy services can be abused, and TG doesn't even pretend to be that.

I think he got arrested because happening to be in Baku for a couple weeks and then still be there at the same time with Putin-Aliyev meeting, and their agreements apparently having intersections with Durov's activity, is openly weird.

Useless. Current allegations are related to the absence of moderation. Moderation of public content, in public channels or chats. As you can guess, end to end encryption does not protect public content.

E2E is just one part of the puzzle, you got to have a open source P2P or federated architecture as well, otherwise you have to trust a nebulous company or person intrinsically. People change and companies can be bought, but you will be stuck with their platform in order to contact your acquaintances, and changing that means loosing your contacts.

That is why the DMA is important. But you will be even better off just directly choosing a chat platform, where the users are in control.
