I have some cheap(east) VPS with OVH that I didn't even know had DDoS protection until I got the emails that my host was temporarily migrated to mitigation infrastructure during a DDoS, and back a few minutes later. Was pretty impressed especially since I don't pay extra for it or even know I had it!

it benefits them, since DDoS will take down not just your VPS, but more infrastructure along the way. there are probably downsides as well, like blocking crawlers from search engines
