Look at the details of that report. They're measuring by _number_ of tweets rather than impressions. Hate speech impressions are down. i.e. if you want hate speech you have to go out of your way to find it using bots. Normal users are seeing them less after the purchase.
It's really tiring to counter so much misinformation about this that flies about.
Hate speech IS up. The claim was "hate speech is up". Impressions being down matters to the impact of the speech, but the claim stands - hate speech is up. You can claim it doesn't matter (and I might agree with you, since impressions are down, people know what to expect now, and the increase is significant but not huge at this point), but you can't honestly say the claim "hate speech is up" is misinformation.
Edit: Actually, I had the claim backwards - YOU said it was DOWN, and you were wrong (according to the report). So to correct myself - the person refuting your claim was right, and spread no misinformation.
I'll retract my opinion that "hate speech is down" as it's apparently difficult to measure but I am going to continue to say that "hate speech is up" is at the very least "highly misleading" as it gives the impression that the platform is worse for minorities than it was pre-acquisition. The reverse is the truth, given the lower impressions of hate speech, it effectively means that those that would verbally attack minorities are being highly squelched versus the situation before the acquisition. That's all around a good thing.
The content moderation is basically nil now so tons of racist content is propagated throughout the network.
