I'm guessing their argument is based more on how TNG, outside of Trek-circles, is largely forgotten these days...
Except it isn't...Patrick Stewart is still known for Picard as much as anything, and the spoofs that turn up, from kids shows to stuff like family guy or futura a are as likely to reference TNG as TOS. Thingymajig actor chap, Scots fellow, whose name escapes me...James Macavoy? Was probably more excited to essentially be playing Young Picard than he was to be playing professor X, and says as much in interviews when he was publicising Days Of Future Past. (If only he has been older when they made Nemesis eh.)
