If this only applies to new sales then there is nothing that must be broken. The developers would need to choose technologies where license allows this. Those that don't wouldn't get new sales from game developers.

It's the same as GPL and similar licenses. If you don't want to publish your source that contains trade secrets then don't incorporate GPL licensed code.

There are also already various laws which compel certain types of speech. Consider things like nutrient labels or ingredient lists.
