I am not aware of any major content provider who still has
any agreements in place that don't say anything about routing
past the provider's network.

Some weren't paying any attention when they signed up initially
and didn't get the specific provisions.  But once bitten by such,
renewals Do Not Happen without additional clauses being inserted.

I don't rule out there still being such agreements, but I think that
anyone with a clue and enough traffic to think about multihoming
has been exposed to this and should have insisted on some legal
protection about best-effort to route to rest of world.  It never
fails to impress me how many people have little clue, though...
