If there was no TikTok/Twitter etc, people would have heard of it from politicians and NGOs and some people with other motives would have used it.
I wouldn't say that this is necessarily Twitters fault and I don't think these comments should be blocked. People gravitate towards easy answers to their problems and blocking doesn't help because there's private groups and real life communities where that kind of stuff is discussed.
I think, people concerned of social media are also seeking easy answers like those concerned with the mass killings of Palestinians. They all have valid concerns but their desire of easy solutions is misguided. It's so easy to say its the "evil jews" and its so easy to say that social media companies are radicalising people. Only if they can do this thing they will fix it, they think.
There's no easy solution to Gaza-Israel conflict, there's no easy solution to people communicating BS with each other.
As an example, this event organised by jewish people to talk about peace have been marked as antisemite by the government and lead to funding cancellation of a cultural center.
