They run hundreds if not thousands of sites and are one if not the only sites most well known for DDoS protection. They have nothing to gain from DDoSing Voat.

Wouldn't be a bad plot, with voat being trending at the moment, it would definitely give them exposure.

The risk of getting caught would be way too high for them though, that's something they could never recover from.

I think it's safe to say they were the good guys :-)
