Thanks- that's what I do also (but with noscript). I'm just calling their attention to the issue that turning on trackers != turning on ads. And, they shouldn't be using trackers.
If you use Ghostery you can whitelist different "tools" independently. It's very easy to allow all ads and block all trackers. You can also decide to only block certain ads or trackers for specific websites.
I've subscribed to the Atlantic dead tree version in the past. I have no problem with that. But their using trackers makes be suspicious that paying won't make the problem go away- only that I won't see it anymore.
EDIT: I could clarify: I tried whitelisting the ads and that wasn't good enough. They wanted me to whitelist the trackers too.
