Some of those items read very strange, and i doubt they can be even enforced (worldwide)? Can they actually demands things like: "you don't make and sell more than 20 product items using the same (or a substantially similar) Unique Design. This means you can make 20 T-shirts using Design A and 20 T-shirts using Design B, but you cannot make 21 T-shirts using Design A; nor can you make 20 T-shirts using Design A plus 3 mugs using Design A;"
