What does playing around actually mean so to understand what Apple Corp deemed illegal, and if running a full bitcoin node becomes legal does it matter if my full node is a hardcore properly configured one or an umbrel one?

For me playing around means never putting real money into the system or if you do being aware that you are spending money to play around like buying a movie ticket or a video game. If you’re such a hot shot Linux admin someone will pay you good money to make that your job. But you will never be able to build a 100% secure online system so you will have to bank any “winnings” and of course then educate yourself on paying your fair share of taxes when you bank those winnings so that we can maintain our roads, kids can go to school and you have some measured guarantee that the food you buy is not poison, etc.
