That first part is true, and
they seem to be absolutely right to do so.
Insomniac did thing on it ~15 years ago now, explaining how they were done trying to hit 60 FPS when, apart from a small subset of people that moaned loudly about it, critics scores, sales and fan scores didn't seem to be care about 60 fps vs 30 fps as long as it was consistent.
Ratchet and Clank PS4 is 30 FPS and people were gushing over the visuals when it came out. I actually think R&C PS4 is a pretty crap game, but thats besides the point. It is pretty at times.
Horizon Zero Dawn, Uncharted 4 both 30 fps. Last of US on PS3 30 FPS. They take all the plaudits, hardly anyone cares.
That being said, it would be nice to do 60 fps at some point
