Can someone explain what 'Shopify Editions' really is?

Thank you, your explanation clears it up very nicely. The concept as presented by Shopify is so confusingly worded and presented that I had no understanding of even what it was or if I needed to do anything to engage with it. I really hate when platforms present consumer-facing information that is worded as if the consumer is an employee of the platform. It betrays a complete lack of fundamental understanding of who their customers are, and shows how little they care about the customers understanding of the platform they PAY to use. It’s my firm belief that shopify wants their customers to be confused and unable to understand how to properly use the platform, so that shopify can turn around and sell “apps” with paid subscriptions that solve “problems” that shopify themselves intentionally create. I regularly tell people to avoid shopify because of exactly this kind of thing.
