Netflix makes heavy use of Amazon Web Services, specifically S3 Buckets. I’m sure there’s a special deal worked out with them as an anchor client.

Malls do the same thing. While they’re not in direct competition in the same sense as Google/Spotify or Amazon/Netflix, some stores don’t even pay rent in a mall because it’s expected that they’ll drive traffic to the rest of the stores. 90% sure Victoria’s Secret, Macy’s, etc are some of these anchor stores that very often pay little or negative rent due to the sheer revenue generated by other avenues.
