No, native app is not platform lock-in... You just need to choose the OS correctly and also the app. The SDK for advertising can be present in both. The sandboxing does exist in OS. And you clearly loose control over the App when the website is taken down while you can still use the native app. If native platform remove support for USB or BLE, your web browser cannot use it either so no USB/BLE at all. Users can choose but native is a lot better for privacy and security if the OS and the app are chosen correctly.
