Yes, if they get enough people doing chargebacks. The challenge is most of these big co's seem to be in the "too big to punish" camp. This is both you need a large amount of chargebacks and perhaps they may not want to fire the companies (though this is speculative).
> At least in my circles, the sense of security from having charge-backs is a huge reason a lot of people even use CCs.
I'm with you that this is still important and valuable because many companies don't blacklist you. Furthermore I'd rather have that protection and testing a service which could be no service than no service at all.
