Part of what makes Amazon Prime so great is that you don’t need it, because it’s luxury. Non-subscribers can use Amazon the same way that subscribers can, and the company doesn’t purposely detract from the regular experience in an effort to bully its users into paying for premium experience. It looks like that’s starting to change, however, as Amazon has started locking a number of video games behind a Prime membership, meaning you can’t even purchase the games on Amazon if you’re not a Prime member. Pair this with the reports that Amazon has been slowing down shipments to non-subscribers, and you’ve got some early warning signs of a disappointing trend.
