Well the creators are allowed to say "no". The network does not write the plots or come up with the characters. Ultimately the final decision still comes down to the writers.

I'm sure Tom McGills does like Gwent, but there's a very large team that does not just includes him. He doesn't control what happens in every individual episode. Not every writer was necessarily opposed to the breakup.
