I'm not a big fan of Fedora's toxic adoption of shitty technology, but it would be unfair to lay a lot of blame on Fedora for this. You aren't forced to use DNSSEC, it's just going to use DNSSEC if a domain is set up to use it. The people to blame for the adoption of DNSSEC are the asshats that try to push it as a solution for all our problems, or mandate it across organizations.

Where Fedora does have blame is the extensive weasel language they use to pretend DNSSEC is the only solution for providing "trust". DNSCurve doesn't exist according to Fedora.
