I'd take that bet on a heartbeat. Cloudflare will absolutely remove others from their service in the next 5 years, but they will be kin to 8chan, the daily Stormer, and kiwi farms. As long as we can agree that none of them would satisfy the conditions of your bet.
The difficult part is how to agree that these sites are not “kin to 8chan, the daily Stormer, and kiwi farms.” Like I said: that will be the outward justification.
Look at how MAGA Republicans have been labeled violent fascists and domestic terrorists. Look at how the same labels were applied to the Canadian trucker protests. Very similar with anyone aligning with Russia in the Russia-Ukraine conflict.
A number of these people legitimately are domestic terrorists. Domestic terror groups helped setup Jan 6 and the trucker protests. If you attend events setup by domestic terror groups, well, there's a good saying: "If there’s a Nazi at the table and 10 other people sitting there talking to him, you got a table with 11 Nazis."
Is it so impossible to imagine that it was arranged for some of these fringe individuals to appear and then be over-represented in media coverage? What easier way is there of immediately discrediting an anti-establishment popular movement in the minds of witless liberals? Let’s recall that the funding and utilization of Nazi and extremist groups by five eyes intelligence agencies around the world is well documented.
