Cross referencing these different things in the article to other apps that exist was my first thought as these seem pretty generic and probably reused from somewhere else.
They likely did a search-and-replace on the brand name, so you had strings like 'your invoices from Home Quarantine inc' in the code.
Not a bad thing per se, getting the app out the door asap was definitely a priority in that project for understandable reasons, but funny nonetheless.
