It is up to you to harass your visitors or not. CloudFlare does not enforce it. You can disable the firewall if you don't want that kind of protection.
They enable what exactly? It's a useful tool and should definitely be activated in some use cases.
We might argue about whether it should come turned on by default or not, but as far as I remember the default setting is not a strict but a moderate protection level anyway.
Not sure what point we're trying to make here. Any other firewall/CDN/WAF enable you to do the same thing, to the point of many also providing ready-made protection profiles... what makes this specific member of that group special? Can you clarify?
