Funny that both Grindr and BLM disagree with you. I wonder which part of the political spectrum does find these kind of measures appropriate...
Providing features which allows user to have a prejudice (this race is more suited to my entertainment needs than another) based on race is not racism? Ok
On Monday, Grindr framed the policy change as one motivated by solidarity with protesters in the United States. "We stand in solidarity with the #BlackLivesMatter movement and the hundreds of thousands of queer people of color who log in to our app every day."
It's nice when common sense bears out in the research.
Even if you disagree with what Twitch is doing here, you can't possibly suggest that it's the same thing as what happened with Grindr if you're actually engaging with this discussion in good faith.
