From today onwards I am boycotting Steam, I will no longer buy games there, itch.io needs to allow people to make payments with bitcoin
The issue is that they would only have to be able to accept bitcoin. Visa/MC/Payap have threatened to withold their services if hosting the games. So they would lose a major funding source. What needs to be done for US citizens is to contact your reps and ask for the Fair Banking Act to get passed. This prevents payment processors from making the choices of what we can spend money on.
