There are a lot of laws and not all of them get updated, as regulatory bodies only have so much time, attention, and political capital. The EU's cookie law still requires a banner if your site uses a cookie to store something like preferred language or default location (even if it's not tied to a specific identity), as those aren't considered "strictly necessary" cookies. GDPR's right to be forgotten hasn't been updated to stop abuse by people who want to hide their past crimes or controversial behavior. The EU's laws on self-driving vehicles still restrict maximum lateral acceleration and lane change behavior, forcing vehicle manufacturers to gimp their software in the EU.

The new USB-C law could be improved significantly if it was a tax instead of a mandate. There is a dollar value associated with the cost of recycling proprietary chargers. Taxing that would be a source of revenue for the EU and allow other chargers for purposes that we can't predict today. The current law is purely a cost center for both governments and manufacturers. And since everyone agrees it will need to be updated at some point, it's the law equivalent of tech debt.

I'm surprised at the responses I've gotten considering how I didn't say I was against this law. I just said I'm not sure if it's a good idea in the long term. And so far, the replies haven't engaged with most of my points. The EU's mandate helps big companies at the expense of small ones, does nothing to discourage electronic waste unrelated to chargers, and makes it harder to switch to whatever will come after USB-C. Yes it's possible for the EU to change the law, but considering they've started with a flawed law and they haven't updated quite a few other laws, I would bet against this law getting updated promptly.
