unless Reynolds "banded" together with another major DMS provider to "price-fix" or do something else outlined in the Sherman Act.
I think coordinated actions among sellers to restrain trade in a specific market for their own benefit can violate the Sherman Act, even in the absence of a monopoly or majority control.
With the Sherman Act being a Federal Law, it's application here is likely to be more dependent on how it affects interstate commerce.
