Huh? You do realize that if something happened two years ago, today it still has happened, right? History doesn't mutate after it happens.

The article supports Cailian's claim, saying, "But the uprisings brought mainstream attention to abolitionist arguments that the problems are institutional, and that the only way to reduce harm is to take power and funding away from police."

He's saying that got some traction, and the article confirms it.

Maybe the present progressive tense isn't entirely warranted if one is living very much in the moment because the effort has past, but if one thinks on a larger scale about contemporary trends, present progressive is perfectly reasonable. Certainly not something that warrants calling it misinformation. (Maybe "not as clear as it should be" is a fair critique.)
