Yes, the internet is much bigger than it was in 2003, and it needs more complex protective tools. The fact that you haven’t noticed cloudflare when it is working is a sign that it is, well, working.
And the fact that your favorite sites aren’t down more often is yet another sign. Downtime due to DDOS attacks alone would be so much greater without cloudflare than downtime due to cloudflare currently is. Your perspective is a pure lack of knowledge and an excess of confirmation bias.
Perhaps not the whole world, but I’m many/most countries, the larger structures, like government and business, absolutely are anti-intellectual. Nice to have an academic friend group, but that doesn’t change the fact that capitalism makes education less accessible in order to rely on an undereducated workforce, and then politicians push it even further for the sake of easy control.
