Even if everything you're saying here is 100% true, I don't see how it would support the accusation that Tim wants to force everyone to use his launcher, which is what I quoted and took issue with. Can you explain how the lack of a shopping cart and some mistaken bans are meant to prove the accusation true?

That's a problem with their anti-fraud not a problem with missing a shopping cart. And that's probably been fixed.

iTunes, Apple App Store, Google Play Store, even Amazon Kindle book store, all are missing carts. Because a one-click buy is way easier to navigate than adding to cart, going to cart, and then finally checking out.
