Okay, so I'm under false assumptions

Yup, you are indeed.

the rules say repeatedly Telepathy works as TEC and could be easily made for actual damage.

Nope, they definitely don't.

Nowhere in the Power description for Telepathy is the word 'damage' even used.
It doesn't say you can't have a move that would... give someone a headache, or something... but it certainly doesn't say anything to give the impression that such a move would rely on TEC rather than ATK...
You could claim that TEC would contribute to landing such an attack by bypassing mental defences, in the same way it normally would to bypass physical defences by aiming properly... but even that might be a stretch. Like Gunther says, you may still need Homing.
