(1) I didn't downvote you.
(2) I said something similar but critically different:

Building a streaming platform that expects to have multiple billions of dollars in revenue across hundreds of millions of users is going to have enormous fixed costs that cannot be trivially scaled down if user counts are lower. If they plan around a much lower user count they can scale it down at that planning phase, but not after the fact (at least not easily).

The intended size of the platform dictates the fixed costs.

And...
(3) The data you provided wasn't fixed costs. It was variable costs like server time, music rights, and bandwidth.
