Note that this behavior is not enabled by default. Websites behind Cloudflare need to opt into it, and they can choose which security level they use (with higher levels necessitating more CAPTCHAs).
Also, as someone who browses 100% of the time with a VPN, I hardly ever encounter Cloudflare CAPTCHAs. I've also been encountering less of them when using Tor; it seems Cloudflare has made progress in their efforts to reduce friction for Tor users. On the other hand, Google search frequently doesn't work at all - it refuses to serve me search results and doesn't even offer me the chance to solve a CATPCHA.
