Is the kneeling by pro athletes hypocritical?

Kneeling during the national anthem started by Colin Kaepernick is supposed to show solidarity against oppression. Basically, America is evil and until the oppression in our nation is gone, the protests need to go on. He even pushed to have Nike (one of his sponsors) pull an American flag designed shoe from the market because the flag “was an offensive symbol”. Meanwhile, other pro athletes have joined in the castigation of our nation for the oppression of blacks. And Nike is sponsoring some of these players.
But Nike uses slave labor to make their product. The Chinese ship Muslim slaves (Uyghurs) to factories to make products. Nike, BMW, Apple and others use these “workers” to make products and pay next to nothing for their services.
Is it hypocritical to protest America “oppression” and make tons of money from slaves in another country?
