I wouldn't call chrome a walled garden, it is just curated list, if you don't like it you don't have to use the "store" . You can still install the extension without the store. There are plenty of extensions they reject and you can download, same for android(for ex:F-droid). You can maintain your own curated list in your own app store. Google will get sued if they allow listing in the store.
