Huh, didn't know about this piece of lore. 

I'd kinda assumed Telepathy was linked to magic and so were both weaknesses for Superman.

I honestly have never viewed telepath as being in the magic pile. Especially with how frequently it shows up as either a racial trait (Atlanteans, Martians,etc) or a mutant/metahuman power.

Now whether or not this is part of main canon, I haven't fact checked. Superman has been able to use a telepathic link for communication before, but on Smallville which is obviously a heavy influence, Clark's thoughts were safe from telepaths.
