Apple also uses a lot of infrastructure that they don't pay for on their devices. Everything from open source code used in Darwin to public internet infrastructure. Besides that, if that is the reason that they don't want to offer this, they could offer a paid subscription for Android users.
The reason they block this is not that they cannot afford the infrastructure, it's peanuts for them. It's because they want to continue maintaining the schism in the US where Android users are stigmatized for green bubbles, pushing them to buy iPhones. (AKA exploiting teenagers' insecurity for profit.)
Apple has every right in the world to use open source software if they comply with the code's license. The Beeper client has no right to interact with Apple's servers in a way that involves faking an Apple authorization.
Apple has chosen not to provide an iMessage client. The mere possibility for one existing does not mean Apple can be forced into providing or tolerating one, given that it involves cost on Apple's server side, no matter how small that might be to them (how can you even tell?).
The fact that US teenages stigmatize each other has nothing to do with Apple's business. Apple has always advertized iMessage as an Apple-only messaging platform. If teenagers are to be protected here, it is up to US legislation to create a law that prevents the undesired behavior. Until such a law is present, what Apple is doing is legal, and what Beeper is doing is probably not, they're certainly creating server upkeep costs that they do not pay Apple for, despite Apple telling them clearly not to do so.

I'm not completely down on the implementation details but is there really anything "faked" here. If they have a service that client and authenticate against using an Apple ID and I just use a different client with my Apple ID then nothing is "faked". It's just implementing the protocol.

I agree. But if they're going to provide these servers on the Internet without any sort of paid authentication and I can utilize them with an alternative client then I'm going to do that. They don't have to tolerate it.

The Sherman Antitrust Act is broad and vague. It's practical definition depends on common-law precedent. While the system may seem baroque, it offers a kind of stability that has made common-law jurisdictions the preferred arena for most international business across the world. Hence, this fundamentally misunderstands the nature of the relevant competition law.
