Re: I get my APK's...
So you're happy that the APKs you download aren't vetted, scanned and approved as virus/malware free?
You obviously haven't done much side-loading. Most non-Google stores just provide files that are otherwise geoblocked but have already been scanned and vetted. What the change will do is allow companies like Google to provide scanning and vetting a commercial service this would put it on a solid contractual basis as opposed to the current handwaving approach, ie. liability for APKs could be established. Would also give Google a shop window for its code fuzzing and analysis services.
This is an example of how regulation can help spur innovation through competition.
