Did you cry foul every time they used Klingons or Romulans or other familiar species on TNG or DS9 or ENT?
No, I eventually got bored and tuned out. Much like I have with Discovery, still only making it through 12 of the 15 episodes. The Talosians, in and of themselves, wouldn't be a problem. It is when you put it as a cherry on top of callback mountain that is Discovery that it is problematic.
I mean, I know they want to sell the show to as many die-hard fans as possible. But, at some point they are going to have to let the crutch go and stand on their own. Even hardcore fans will only hang around for so long when all you're doing is constantly metaphorically jabbing them in the ribs going "Remember this piece of minutiae? So do we!!!"
