Is it objectively true in general that default sharing transaction-level credit card data - in other words, I can see a (pseudo) anonymous "user ID" column in a table of transactions - benefits all of us more than default privacy? In my estimation yes, but this is a complex question. My point is that the EFF spends no time investigating this in a serious way at all. We live the reality I'm describing with Steam, which is millions of people, it's been going on for a long time, it's conceivable that even broader categories of transaction data may be prisoner-dilemma-style valuable to share. I just wish the EFF would engage with that 1 iota. Otherwise they are just another opinion in a sea of brand-and-celebrity posters.
