IMO the reason Cloudflare took down TDS and 8chan but not the Taliban or Hamas is simply outgroup vs fargroup. [0] The operators, users and targets of 8chan or TDS are all familiarly western but different enough to hate, while islamic terror organizations are so different it's hard to relate to them - sort of like that joke about how the more similar two religious denominations are, the more likely it is that they hate the other.

I don't see this working out well for them when it comes to total negative news. Would we have seen nearly as many requests to Cloudflare asking for 8chan to be cut off if they had not already done so for The Daily Stormer?
