1. This is very literally what already happens, it's called a EULA.

2. In practice this means you are required to personally come to the customer's house to fix bugs (or any other ridiculous edge case that wasn't "fully stated"). As much as I strongly agree the law should swing much further in the direction of the consumer, as GP points out, that only holds until it's your obligation to the customer on the line. "In favor of the customer over anything else" is not a legally viable clause.

> "In favor of the customer over anything else" is not a legally viable clause. I'm sure that legislators could put the principle down in a much clearer way. What's lacking is the will.

That's precisely the problem here. You're "sure" that a problem you don't actually fully understand is trivially solved in a simple manner, when the reality is that this sort of thing is incredibly complicated, and there's a multitude of reasons and competing interests that have resulted in the current equilibrium.

This is the sort of change that requires a country's laws to have to be rewritten from the ground-up, because it invalidates so many assumptions. It's the sort of thing you typically need a constitutional amendment (or at least, a novel interpretation of the existing text) for.

So, yeah, they're lacking the political will for that.
