Surely blindly pushing, yet another corporation into position, where they can lobby virtually anything, is awesome idea. (Nothing against folks from cloudflare. They seem all right, but they will get acquired and/or change leadership at some point).
You might not feel the downsides of having a huge percentage of the internet going through a single provider until it's too late to change it.
I actually quite like Cloudflare, and I don't think they're purposely doing anything nefarious (just following incentives like everyone), but I think caution is warranted.
