Is Tom's Hardware removing it from their article not suggestive to you that maybe it was wrong?
Well, given the fact that President Zelinsky is saying it's right - I am not going to make leaps of logic without factual explanations.
So no, I am not going to infer that they removed it because they were wrong unless they explicitly say as much.
Nor should you.
So he's reporting on what people on social media are saying... which is just continuing the initial misinterpretation of what Cloudflare meant by "Russian bots".
