I don't think that statement makes sense here. In what way is the user of 1.1.1.1 the product? And for cloud services in general, they mostly tend to be subscription or usage based. In both cases, the user is clearly the customer.
I get the "you're the product, not the customer" for social networks or ad-based search engines, but certainly not for cloud products.
Might be a stretch for cloud services generally, but for public dns resolvers there's definitely an argument to be made: a) you pay nothing for the service, b) providing the service costs money, c) the provider benefits indirectly from the added insights and market power of user traffic
