The CG was a dealbreaker for many, but the Max viewership seemed to save it.

I’m pretty sure Demarco has claimed every original so far has done great, his bosses were super excited about it, and S2 was possible. Then 3 of them got written off, so I don’t think Demarco is a good source on how the originals perform. 
 

Plus, I have seen my fair share of 1 cour anime originals, and this one has all the markings of a single season show, right down to showing the title card in the last few seconds. A new season would essentially be an entirely different show because all the major plot threads were resolved for the cast already.

Also, I bet you anything he claimed there wouldn't be any more FLCL sequels after Grunge and Shoegaze in an attempt to save them from the lacking mercy of Zaslav's almighty pen.
