So we shouldn’t have communities around videogames (or board games), professional sports, traveling, food, clothes, most hobbies, or anything else, because it costs money? Even in a bookbclub, the library won’t have 15 copies of the same book, some people will have to buy it, unless your book club comprises 2 people.
You get what you pay for is exactly right.
So it makes sense to ban discussing games that are not open source, discussing movies not in the public domain and sports that charge for tickets?
