> The new breed of delivery services (Uber Eats, Glovo, etc.) don't give a damn about preferences - they'll offer delivery services for your restaurant whether you want them or not; they won't even ask you for permission.

This is no longer true with Glovo. I've seen restaurants in the Glovo app that do their own delivery. The app shows it to explain why there's no tracking of the riders for example. Or why they can't give you an accurate estimate.
