Anubis is affective against certain kinds of bots and abuse, but wouldn't be that affective against large scale DDoS attacks. And it does have a negative impact on usability, as users have to wait for the browser to do the proof of work, which may or may not be worse than cloudflare's captchas.
Anubis is a partial mitigant of DDOS attacks, since it's less resource intensive to serve the Anubis page than the origin[1].
Cloudflare's captchas are only convenient for a subset of users, I'll bet there'd be decent money in one of the competing CDNs (Fastly maybe?) including an Anubis-like captcha.
