The goal isn't to make money or calculate wallet share. The goal is to send encrypted messages to contacts.

You should look at the percentage of smartphone owners. It does not matter in the slightest how many dollars they have in their pockets. The question is: is the average user going to have a significant number of Android contacts, with which Messages requires plain-text communication to contact.

And the answer for most people is: undoubtedly yes. I would say that most people who are using Messages as their primary messenger for all of their contacts are sending unencrypted messages on the regular.

Completely fair, I had shifted topics from phone owners, to platform relevance to makers on HN.

Your point stands.
