It's a weird criticism, but I think the main point was in regards to Disney's intentions behind it, mainly to cash in on a perceived concern of the audience rather than for any altruistic reason. But it's really a nonissue because the cast is great and the diversity is something that does legitimately deserve kudos, regardless if there was any soulless, greed-driven machinations behind it.
On the whole, I think there were some good points discussed in the review, ones about the larger state of Star Wars as a giant corporate entity and the internet's relationship with it. Things that are worth examining, particularly from someone who had a hand in its propagation. It's very important to always remember that for as good as the films might be and as good as the creative choices seem to be, Disney is still one of the world's largest businesses and desires nothing besides getting you to buy their products in perpetuity forever. On the other hand, Star Wars has always been a commercial behemoth. I don't think it's been fundamentally changed so much as been made larger.
With TFA itself, it's more of a mixed bag. Some points, good or bad, where right on the money and some weren't. The lack of sex, for instance, is kind of odd to me. I get that it can be used to easily inject humanity and sympathy with the characters, as it was in the OT, but I don't think it's always a necessary prerequisite and I didn't think it was needed in this film. I bought Finn and Rey's friendship because of their chemistry as friends, same with Finn and Poe. They were engaging and human characters because of their humor, rapport, and the fact that they spoke and acted like actual people. They certainly were not boring.
