Ad-blocking is a separate matter. VPN apps which do not block ads will continue to remain in the App Store, such as the one being discussed here (Onavo Protect).

Not being pulled out is not being booted. It's just a warning.

Booted from the store is what I should have said.

Maybe de-listed is the better term.

De-listed plus impossible to get new ones approved.

You should correct your original statement then.

They are being pulled from the store. Too late to edit, sorry for the vague shorthand.

This does not apply to the discussion at hand though, Onavo Protect does not block ads. It will not be pulled or de-listed.
