Campaign against the patent system. Don't expect public companies not to use the rules as they exist to their best interest. I don't even see anything unethical in wanting to keep some exclusive features (although 20 years seems too long).
I do also think that Samsung probably did cross the line between taking inspiration and wholesale copying and attempting to look like Apple.
Separately, I'll note that "blame the game, not the player" rings particularly hollow when the players have plenty of influence on the people who write the rules.
Fair point on influence of the rules although I don't recall any of the tech giants opposing software patents or patent exclusivity. That certainly includes Google. If you can point me to a smartphone manufacturer that opposes software patents or design patents (registered designs in the UK) I would be very interested although I doubt I'll actually become their customer as I'm already locked into an eco-system!
Most people point at the physical design of Samsung phones to make this point, but in all seriousness Samsung just plain didn't copy the iPhones design. Take a look at these two products Samsung made, both of which predate the iPhone and both of which show the exact design language that Samsung has used on the Galaxy * products:

Not somewhat similar to the design language, exactly the same. From the rounded corners, to the bezel, to the single button on the bottom of the device. This was Samsung's design language before the iPhone ever existed.
