This is precisely my fear. Cloudflare is using price as a selling point.
For people with just a few domains, price isn't important.
I have 5 domains with hover.com. I'm happy to pay a couple of bucks extra per year to know that there's real support. I can call and get an answer in 10 seconds.
Granted, I've never needed to call support, but losing my domain would be a huge disaster with no website, no email, and cost me hours of time. I see no reason to risk anything to save $5 a year
