"Trash apps" and "more todo apps" isn't what this rule is preventing. It's preventing "apps" that are essentially just a viewer for a built in static text, PDF or image file. Which can and should be replaced by a text, PDF or image file, or a web site.
Not at all - it is preventing people not having a company from uploading their apps.
If you setup a company you still will be able to publish crap apps, it might not be profitable as it was before due to bureaucracy overhead - but the same for people who want to make useful apps but don’t want burden of setting up company.
Meh... That website might not be available in offline mode. I may want 5 PDFs in an app because it's still easier to find the app than it is to search through 'files' on a device that wasn't designed for managing files.
