I was just reading a Reddit thread about DNS problems and was mildly surprised by the number of respondents claiming Cloudflare is the panacea.
Centralization is a military-grade problem.
Cloudflare is centralization.
Cloudflare, whether you like to think about it or not, is a weak link, a spider's web, a tightrope walker standing on one foot, a wobbly top, a disaster waiting for its time to be revealed.
But far worse is the culture that currently exists, a culture that sees no danger here.
