There are laws against bundling, but not sure they've ever been enforced in this field, nor who would do the enforcing. Justice? FCC? Either?
After reading the links provided of court cases, I would say it's the opposite. Bundling is very legal and can be beneficial to the consumer. What could be illegal is the result of the bundling, or another way to say it how they are structured. If the result is a monopoly for instance, then perhaps that particular bundling packge is not allowed but not because bundling is not legal but becase of what it caused.
