> should we be surprised that Apple are using that which the law allows them

Yes. Your argument seems to be that we should expect companies to behave exactly as badly as the law can possibly let them do so and that they should receive no reproach for doing that. If you use this argument then you are implying that the law should enforce good behavior in every single thing every company does, since there is no other force to make them do good things (remember, you just argued that nobody should complain about what Apple does because it is legal).

Clearly the above is ridiculous and the whole premise of "free" societies is that people and companies are granted wide freedom to do things and the law only regulates the most severe of these and that people will motivate good behavior by each other and companies by shaming them and judging them and refusing to deal with them when they behave poorly.

So yes - when Apple behaves badly they need to feel judgement from the community and this is how it happens. The company does something bad (suing over a frivolous feature to block an entire competitor's product), and we express surprise and shock that it did such a bad thing.
