+1 Since the Sony/BMG scandal, I've made the same explicit decision. To me it was proof that Sony was and has never been interested in consumer rights, and so I choose not to have that relationship with Sony. I agree with @pr0t0, vote with your wallets if you don't believe a company is conducting itself ethically. I'll forgive Sony, when their business practices change.... it's going to be awhile.

Bottom line: Sony does not care about customers. Since the "Sony/BMG root-kit" fiasco, it was clear to me that the ethics and the consumer friendliness of Sony didn't deserve my business. I've boycotted Sony products since then. I even don't buy blu-ray discs because Sony benefits from the licensing. What else, oh yeah, the lack of security and failure to protect consumer personal information and your credit card data is more proof that they aren't doing the right thing for the customer. Now this. Sony doesn't want to respect your rights, too. Seriously Sony, WTF. In my opinion, I was right to boycott Sony before, and this doesn't change anything.

I meant to comment the following: This blog posting is not just an explanation of Mozilla's very justifiable action, but a clear message to all other CA's of what's expected of them.
