 From the users perspective TLS is most often not end-to-end (like for

be decrypted and therefore which laws will be applied to the sent data.

Would be nice if you could ensure that my messages will not be seen by 
intermediaries like Facebook, Google.

presents a certificate. The user may have a need to inspect the traffic 
to defend against attacks and maybe just to prevent ad spam.
