What? AWS and GoDaddy are not terribly expensive. GoDaddy is incredibly common. I don't know about Rackspace. Together they make up a large chunk of the Internet as we know it.

AWS and Rackspace are terribly expensive, GoDaddy is huge in the domain space but not particularly big in hosting, besides shared-.

Why not look at the likes of OVH, Hetzner, Voxility, Colocrossing and so on. Or maybe try Level3, their business may be a bit different but they're HUGE and certainly forward abuse reports.

I'm no expert, but a quick Google leads me to http://www.webqom.com/blog/2016_web_hosting_market_share_tre..., which states that GoDaddy is the most popular hosting provider out there.

Yes, Godaddy sells lots of shared hosting at insane margins.

These insane margins help pay for a big abuse department.

Most dedicated hosting providers don't have as big margins because they can't stuff 1000+ customers on one server.

Most dedicated hosting providers don't have very big abuse departments, or any abuse department at all.

What does price have to do with not stripping contact information from a report?

It's got everything to do with having a bunch of humans handling your abuse reports. It's also one of the reasons why IP reputation is so important to these hosts.
