mautrix/telegram is a bridge between Matrix and Telegram. It mostly lets users of Matrix contact their friends who use Telegram. It is not a fork of Telegram and has nothing to do with the Telegram interface. (Note: OP wanted to use the Telegram client with a non-Telegram server. If you know of a Matrix client which looks and feels like the Telegram client, thats what theyre after.)

Well, was it locked?

There are more reasons, as LetsEncrypt might be more restrictive on what you can get (for example, you cant get a certificate for an IP address from them). But, as 99.99% of usecases do not require anything like that, go with letsencrypt until you know of a reason not to.

What should it do instead? I think the only reasonable action would be not showing it if the licence file was changed.

Bottom left. Matrix client.

It doesnt even matter, TTL is only decreased when routing. Ethernet frames have no such concept.

Is this post about Github seemingly detecting an incorrect licence? The project was relicenced in a later commit, so I dont think this behavior is entirely wrong.

Just wait for the trolley to pass and then enable an autoclicker

Why would banking be an issue? I get that its a target, but I really would expect a bank to take care of their TLS.
