The whole idea of slipping paid advertorial content into what are billed as "research" kind of gives the lie to this whole thing and is why I never turn these on in any product. Which is also why it's now "opt-out" by default, and why it will eventually not be an option at all. It's all for our own good, you see.

If that didn't happen in this case, then I suspect it's probably a bug.
Wrong, as far as I see: Looking in my about:config, I see
app.shield.optoutstudies.enabled=true
browser.onboarding.shieldstudy.enabled=true
That means that the user must actively take steps to disable them, if he knows that they exist and where he can disable them.
Every time the user creates a new profile, and most probably also when he "refreshes" an old one, he has by default the studies allowed.
It's even worse in other aspects: through the UI the "Allow Firefox to install and run studies" can be unchecked but it doesn't change the value of "experiments.enabled" to false in about:config.
Apparently the "experiments" allow Mozilla to install the "experimental" extensions to any user, without him knowing. And these extensions are invisible in the GUI! Even if the user goes to the about:config and sets extensions.ui.experiment.hidden to false, it will be automatically set to true again.
It all seems sneaky and deliberately obtuse.
According to the Wiki page I linked in my previous comment, global settings shouldn't even matter in this case; since each SHIELD study must be opted into on an individual basis. (Or at least, that's how it's _supposed_ to work.)
Edit: Looks like the wiki was updated to state that some studies can be opt-out rather than opt-in. This also seems in-line with the documentation for SHIELD, which has a section on opt-out studies: https://normandy.readthedocs.io/en/latest/user/actions/opt-o...
Whereas studies collect usage data.
It's nonetheless not obvious to me why you were downvoted; I don't know if someone else was annoyed at your definition of "new" or whether there were other dubious claims in your comment. Perhaps privacy advocates are just too exhausted and cranky to explain themselves again.
