It's an obvious abuse of their monopoly to suppress competition. Most kids use iPhone and for the general public in the US iPhone has >50% market share, so to expect most people to stop using iMessage to get better support with Android users is not happening, and it's silly to think that will change without a change in laws, so most kids end up getting iPhones so they're not left out.
Remember, this is all a very arbitrary restriction by Apple that lets them take advantage of their monopoly to suppress sales of competitive products. That's the illegal part.
