It's "a-ok" because the advertising companies are racist - as they've generally always been.

I've been pondering a thought that we need to stop treating racism as something like a witch hunt, and analyze it more like poop. Something that will never be eliminated, but rather is everyone's responsibility to minimize. Anyone can get some on their hands by accident, laziness, or dealing with a problem. But you don't come out of the bathroom waving it around and expecting to be appreciated. And if a bunch of people started proudly declaring that they shouldn't have to wash their hands and generally validating each others' slobbery, they'd be rightfully shunned.

This framing has some nice results like the contortions around "reverse" racism and the whitewashing of "positive" racism as "not racism" aren't necessary. If you're engaging in collectivism based on race, that's racism - regardless of whether your intent is "good" or "bad". And sometimes that's inevitable (cf "dealing with a problem"), but that doesn't mean it's ever something to really be celebrated.
