> Sony is the only platform that has "legal hurdles" preventing this?

Not all companies "move fast and break things" in legal matters. We don't know the full circumstances, but Sony may have evaluated the landscape and decided the liabilities weren't worth the potential profits, while Nintendo and Microsoft looked at the landscape and decided that the profits exceeded the liabilities in this case.

It's for the same reason that you find Wells Fargo or Facebook committing transgressions that other banks or social media sites may avoid.
