The judge ruling is kind of a stretch of that law. Because it was first conceived to avoid forcing consumers to buy 2 items together (if you don't buy X I can't sell you Y), or putting quantity limitations (you can only buy 4 or more of X, otherwise I won't sell to you). Of course you can do promo combos (3 for the price of 2) but that shouldn't be the only option, the consumer needs to be able to buy the standalone product.

Also where does it end. Do they also need to provide you the wall outlet? And the wires to wire that outlet to your electrical panel?

It does seem that if it works with a standard USB or USB-C charger they should be fine not to include it to provide the consumer choice of what charger they want to use, be it Apple, third-party or an existing one that they had lying around.

Not really. A game is content for your console, not a feature.

A better analogy would be selling a pre-assembled PC without an operating system. And this is illegal in Brazil, although this law isn't strictly enforced.
