This entire issue is not going to go well for wordpress, developers will just move on to something else, perhaps something better than wordpress, just look back in history and see how being a narrow minded prick can harm your business.

To be honest with all the bot net attacks, the abuse of xmlrpc.php with no admission that its a bad idea that should be removed, just proves in my mind that wordpress is going in the wrong direction.

You can warn the guy about to drive over an unsafe bridge that there is a problem don't go but you can't stop him from going into the river.
