You have to blame Star Wars (Disney or whoever) itself for this. They knew everyone would see "Yoda." Star Wars is a one trick pony, and every one of its movies uses someone from the original series.

Prequel movies: Uses Darth Vader and Obi Wan. Sure, he was Anikan Skywalker, but nobody cares about that. We only care that he will be Darth Vader.

Rogue One: A good movie, but just an extension of the first movie.

Solo: Has to be a back story of an existing character. By the way, it would have been much better if Han had given himself the name. "I'm by myself, I'm solo."

Disney trilogy: Was basically a retelling of the same story. Had to have Leia, Luke, Solo, Lando, and the droids. Can't rely on new characters.

Star Wars can only tell one story, even if it's a good one. It's like they can't have a movie or show that doesn't have something to do with the original trilogy. And we can't forget the toys. We know every character design has merchandising in mind. Kids want to buy a "baby Yoda," not a whatever his name is (I haven't seen the show). They wouldn't have made him a new alien. I predict that we will see a "baby Chewbacca," or a "baby R2D2."

Yeah, the first thing people call something just sticks. Also many are too lazy to remember his real name.

The show is called "Baby Yoda And Friends" for a reason.

It's actually a really good show, though.  Definitely the best Star Wars thing made since Return of the Jedi.
