Good point. You are not dependent on Cloudflare, though, you can use other similar services or open the port on your router if it supports it. And if you pay for it, you can get an SLA so that they can't mess with you by terminating your project.

I would still consider it very nice of them to offer this free service that let's you break free from your dynamic IP, crappy router and at the same time giving you protection that you couldn't set up yourself.

I think many people just want to be able to make their device available from the internet - this type of liberty is not really important for many people.
