According to the OSI definition, you also need a right to modify the source and/or distribute patches.

A lot of them do, especially in the open-core space. THe model is called source-available.

If you're selling to enterprises and not gamers, that model makes sense. What stops large enterprises from pirating software is their own lawyers, not DRM.

This is why you can put a lot of strange provisions into enterprise software licenses, even if you have little to no way to enforce these provisions on a purely technical level.
