I think the most obvious examples of this are the Apple and Android app stores. We know exactly how much money the end user is paying for these, and so unlike the tik-tok video with 800k views we can easily understand their value. We also know Apple/Google are taking is 30% of that value. It's not just individual creators on social media that are suffering from this but also large companies.
Why should any game developer (Epic for example) have to pay the same amount to Apple or Google that they are currently paying to Nintendo or Sony for the same game?
Do we need some new laws to force Google to allow other game stores for Android other than Google Play? Maybe one from Amazon or something. Or some stores in China.
