Agreed.Kinda sounds like a poor user experience for customers, no? Like expecting web apps to be a good stand-in replacement for web apps; Facebook learned the hard way that users can tell the difference, I wonder if Twitter will get the same memo.
But "poor" user experience is better than "no" user experience at this point in the game.
Maybe that's how RIMM sees it?
It's better for them to have a Facebook/Twitter/"insert whatever popular app here" app on BB10 even if it's a hackjob version from Android than to have no apps at all?
I expect there will be tons of bugs using this method. If RIMM didn't do this method, they'd have to get all the way to the back of the line in the iOS vs Android vs WP7/8 app wars.
