I'm surprised we haven't heard more about the increasing difficulty of rooting Android phones. On an open platform I would expect this option to exist in the Settings menu somewhere maybe with a warning that it might void your warranty or crash your phone. I don't think people should be advocating Android as a free/open alternative until this situation is resolved. It's very misleading.

i wonder if someone smells the business model in this.

You mean virus protection software for your phone? :p

How about purposefully not providing Adobe Flash on your mobile dev ice because it's insecure and unstable?

Nah, that'll never work.

It doesn't really matter much that Flash has vulnerabilities, being the #1 google result for facebook login, or a fake login, or a scam email, or a fake app is more than enough to exploit people.
