Mostly based on the fact that Little Muppet Monsters ended up getting pulled when CBS (https://www.nytimes.com/1985/08/25/arts/why-saturday-morning-is-one-big-cartoon-ghetto.html) figured they'd get higher ratings with just an hour of Muppet Babies. Then there's the Young Astronauts (https://lostmediawiki.com/The_Young_Astronauts_(lost_animated_series;_1986)) affair.

Also, Rock 'n' Wrestling in a way when you consider that some guys like Jimmy Snuka and Wendi Richter had left the World Wrestling Federation by the time it made it to air.

Edit.

I wonder if The Young Astronauts is still with DiC or Toei/Marvel. (It is unknown who animated the series but it was definitely one of these two companies)
