Sorry, I am confused what you are arguing here. If you think a usage agreement is binding they are certainly business partners. They may still be business partners or generally covered by tortious interference even if they do not have an explicit contract either.

Precisely. If the API agreement wasn't binding, why would it bother saying Reddit reserve the right to vary the fees?
This is the part that you seem to be confusing.

The API terms were lasted updated May 25, 2016. These include this language:
> a. Fees. Reddit reserves the right to charge fees for future use or access to the Reddit APIs, rates to be determined in Reddit’s sole discretion.
I assume these are the terms that Apollo are bound to. If that's the case, I don't see how you can support your claim. Reddit is using it's contractual right.
