Punishment for ad blockers
No one is more aware than I that the free lunch era of the internet is coming to an end, that said, I wouldn't go on the internet AT ALL without an ad blocker of some kind. Paying for email IS a consideration, but I'd need a little more than you just not forcing me to use an ad blocker. Such as, not doing the big data crunch on the contents and subject lines to aggregate and sell to advertisers, and a guarantee in writing that's the case AND the right to sue you (not arbitration) if you break those conditions. You don't want Congress legislating you? Think about it.
