None of this is a surprise, as conspiracy theories become more and more popular in western countries, the establishment needs to resort to more underhand methods to undermine and silence political activists. Given most are spread online outlets like wikipedia are being heavily censored to mirror the regime's propaganda.Well, we already all knew that they were doing this. Nice to officially know it. Looking at you Wikipedia and your monthly/bi-weekly meetings with DHS, CISA, and FBI. I always knew you were full of shit.
The popularity of conspiracy theories themselves is an interesting topic in itself. The reason they have increased in popularity over the past 10 years, and especially in the last 3 years is because of increased distrust in central government. We saw a similar thing in the USSR before its collapse, people started believing in conspiracy theories rather than state propaganda.
Non Anglophone European societies (Germany, France, the Slavic countries) never evolved a concept of free speech, so for them these crackdowns are normal. The UK and especially the USA had strong belief in freedom of speech and it is having an impact on politics there.
Rather than being a problem, conspiracy theories are a symptom of a problem. If you stop one through censoring sites like wikipedia, two or three more will pop up. The only way they can truly be silenced is for trust in central authorities to be restored.
