Many big companies treat their customers like shit. Just ignore them, and use something else. Why don't you set up a website to advertise your stuff, then use facebook and twitter as well, advertise on boards that talk about the kind of stuff you sell.
Put your money where your mouth is, if enough people do that, that is the only way we can achieve change.
Bitcoin is superior to the Paypal model and existing banks. So do all you can to prompte Bitcoin and make it grow.
The reason Paypal and similar companies treat you like shit, is because they can get away with it. Out of principle you should stop using them.
