It’s completely different. Email is a decentralized network. iMessage is centralized. Email servers, like Mastodon, Usenet (RIP), etc. implicitly agree to federate (usually!) with other servers. All iMessage traffic sent or received has to go through an Apple owned iMessage server and propagate through the iMessage network, so every additional iMessage client has a direct cost to Apple that Apple didn't agree to.
