People should be able to open a restaurant of whatever cuisine they want, but the problem illustrated by the article in question is that when the opportunities available are finite, it's generally white people who get the majority share of the prestige and the money at play.
It's perfectly reasonable to criticize major funding being dumped into a Chinese-themed restaurant run by a white chef because in the real world dollars available for restaurants or restaurants of that particular cuisine are finite, and so it could be potentially taking an opportunity away from a non-white chef.
Obviously all of this is exacerbated by the fact that many white people have the benefit of a higher class, and thus more opportunities to meet people with money and connections or have the money to go to prestigious cooking schools or the luxury of taking a year off and be able to work for pennies in fancy restaurants.
