They usually have a heavy outbound bias in their network (most hosting providers do) and have lots of spare inbound capacity, which can be used for mitigation. Their upstreams can also help with volumetric attacks before they reach the destination.

Exactly, thats the point. If you have a lot of outbound capacity, usually you got a lot of inbound laying around. In our case for example, we're working with heavy outbound transits, which makes it easy to defend against udp reflection attacks (using bgp flowspec) as well as cheap, because they already have lots of large ports / commitments. Without necessary business connections, traffic volume and costly inhouse filters (or years of knowledge to build your own), Anti-DDoS wont be cheap and defending against an 150Gbit/s attack can be quite challenging. In such a case, get in touch with a mitigation provider - it's their problem then.
