I am a bit disappointed that Google has seemingly reversed itself on its openness. While I would want someone poking around in code but I felt wasn't my best work, I feel that this excuse for Google is dubious at best. I believe it is done to stifle competition. They say they want to protect users experience, which you might be able to believe on face value if it weren't for the fact that anyone who had the skills to manipulate the code would inherently know that they are going to change the intended "Google experience". This is not something that a hacker would hold Google responsible for. If he actually could start the glass of milk you don't get mad at the cow because your milk is brown instead of white! Google is afraid that if they allow their code to be in the wild, hackers innovations will outstrip their own. They forgot what made their platform so attractive in the first place. Android OS benefited immensely the beginning from being open source people added features there were leaps and bounds ahead of Apple IOS. For people who are well-informed and made a comparison between the two a no-brainer. If they continue to do this it'll be like going to her door and closing it. And I will be their fault because I've been around long enough to know that there are infinite pathways innovations can take.
