We had XMPP among others, and Apple decided not to be open. We now also have Signal or Telegram, which are multi-platform.
If you say "yeah sure it is, we're even releasing it as open source" then you prevent the product falling at the first hurdle because people want an interoperable solution. Once you have adoption network effect carries you through.
Sounds like most probably a standard corporate lie by Jobs; do you have evidence to the contrary?
Things that they’ve adopted/forked/bought are but there’s not much they’ve started from scratch and released as OSS.
There is almost no expectation of it from people who know Apple.
Promising something unexpected and not delivering is undoubtedly more damaging than saying nothing.
Sorry, I was being a bit sarcastic :P ;)
iMessage isn't the first nor last proprietary chat platform. It's seen as a competitive advantage, just like BBM was back in the day.
Does Android have something similar to iMessage?
No. The parent to your comment means open iMessage between Android and iOS.
Kind of-ish. The RCS support is rolling out slowly. Of course there is a big difference in that RCS is not end to end encrypted. Also, there is nothing stopping Apple from implementing RCS as well, but I doubt they will do.
If there's one thing that Apple hates more than lost profits, it's handing over control of anything to carriers. Cheap-subscription iMessage/Facetime for Android would strangle RCS/Duo in the cradle and put a thumb in the eye of the carriers, while bringing in some steady and significant regular revenue. Let's not forget that Apple is already offering a subscription service on Android, Apple Music. They're not averse to the concept.
It has some massive annoyances but it's very well embedded.
