The article claims the app can only be removed with root access, which requires more difficult and technical steps to attain than running an adb command. If uninstalling the app with adb works and doesn't result in the app being promptly reinstalled, then the article has a significant factual error.

Except uninstallining the app does not equal removing it, as you claim. Removing it from list of apps to load is not removal. Not to mention it resets back to installed and you have to rerun the command.
