Consumer protection is already clearly the focus of Congress, and with the demise of the Chevron deference in 2024, it seems that Congress needs to bind (such that they can) groups operated by the Executive Branch to uphold consumer rights explicitly instead of allowing regulators to navigate the commercial market.

The answer to Why is Congress concerned with details like this? is that the Supreme Court of the United States made it their concern by rejecting an established practice of deferring to expert regulators instead of electable people who probably lack the relevant knowledge and experience.

Tis a silly question. This has the combination of being something that the populace either doesn't care about at all (so no opposition from _constituents_) or rapidly supports (basically any gamer with some form of nostalgia that has gone unmet). As an added bonus it has the potential to set a legal precedent over similar more serious software such as SaaS offerings with a client component.

I could use the same argument to oppose pretty much any legislation that isn't like, solving healthcare or preventing climate change. For any given issue, there's almost always something more important than it to at least some people, so if the best argument against fixing a problem is "there are other problems that should be fixed", that's a pretty strong argument in favor of the fix.
