I think that's a fair characterisation of her premises. For instance, she argues that these outcomes aren't happening because of any systematic quality difference in the products: many centralised products that win significant marketshare are a bit ordinary. I'm not in a position to judge that claim; I tend to avoid products that make gratuitous demands on my personal data so I have less material to compare, but the idea that a universal Electron app is better than a variety of independently developed native apps is certainly not one I would rush to accept.

Her actual conclusion is that in order to create a market whose average members are free, we need more regulation.
