Cloudflare is on the GP's "do use" list, not the "do not use" list.
I think the HN consensus is that Cloudflare is a reasonably safe bet.
Though keep in mind that domains registered through CF must use CFs nameservers, you can't point them elsewhere if you need to. They sell domains at cost so of course they want to keep you in their ecosystem so you might pay for something else.
