Vote with your wallet regards any sort of purchase. By giving money to someone you are giving them the most encouragement possible to continue doing what they’re doing. If you purchase something that you end up not liking, they will still receive your initial vote loud and clear. The gaming industry especially has shown us that companies will happily take both the money and the negative review and say ‘thank you’.
