A friend joined them to get protection because he got beaten a lot. He left again after his first drug trafficking job was offered to him. (and fortunately he was allowed to leave because he didn’t know enough yet)
My schoolmates rented a club house for parties and the bikers wanted to do the security themselves. The have beaten people and kicked one drunken guy lying on the floor who argued too much with them. Completely unprofessional.
This was late 2000s in rural Germany.
I would never put something in my brain that doesn’t at least have a public API documentation. If the company discontinued the product I want to be able to keep using it. Open Source software would be best.
