I think everyone took there comment in the wrong light. They're not defending Google, but rather pointing out that this behavior should be expected from a for profit company, and thus people should have avoided the situation in the first place. Not that it should be that way, but we live under capitalism unfortunately, and people need to be way more skeptical of these companies.
Rather than blaming inaction of the FTC, why not just stop using play store all together and encourage people to use Fdroid instead? Companies will never stop abusing 'e-goods' , it's just not going to happen. People should just get beyond ownership and embrace the advantages of free software.
Well I personally think the FTC should do more, but until money out of politics, it will never happen. And pending some mass upheaval; that is probably in all reality unlikely as long as people are fed, money will almost certainly never be out of politics.
So all the more necessity to encourage people to just abandon these profiteering companies.
