Where are you getting this from? OVH very prominently advertises their DDOS protection that comes with all their products (https://www.ovh.com/ca/en/en/anti-ddos/faq.xml). In fact, they once used it to explain why they increased the prices of their VPSes (https://community.centminmod.com/threads/ovh-increase-prices...).

And they also have a lot of experience with it because they host a lot of game servers which are very prone to DDoS attacks (see e.g. https://securityaffairs.co/wordpress/51640/cyber-crime/tbps-...), so they are definitely “structured to offer it”.
