Superior UI/UX offered by centralized systems is why everything is being centralized.
People will trade everything including privacy and security for ease of use. The market has shown this time and time again.
Your users don't really care about decentralized utopia when your service doesn't work.
I guess bots are hitting CF IPs at large and therefore services might be disrupted?
But if your service is in a category that attracts ddos (like a forum or game) and you ever get enough traction for someone to care (doesn’t take much), it might surprise you how cheap it is to take you down and how limited your options are against a simple volumetric attack.
Cloudflare Tunnel has gotten good enough there aren't a lot of ways to be better left. A couple would be offering e2ee and a less stringent ToS (technically anything other than normal HTML websites is not permitted, though I'm not aware of this ever being enforced, yet).
When someone uses the tunnel, they never have to go outside of cloudflare. Since the traffic ( i suspect) would stay very local.
Perhaps it could be even cheaper in the end for them.
I wasn't talking about the development/maintenance.
