Earlier quoted context omitted.
In your "conspiracy theory", who is Amazon conspiring with? Themselves? Do you know what "conspiracy" means? Do you think a "conspiracy" can be achieved by fewer than two different parties?
Conspiring among themselves would be sufficient for this usage.
Conspire, verb.
1. make secret plans jointly to commit an unlawful or harmful act
2. (of events and circumstances) seem to be working together to bring about a particular result [...]
Was Amazon making secret plans jointly with itself?
Did Amazon seem to be working together with themselves to bring about a particular result?
The sentences above make no sense in English, and neither does using the word "conspiracy" when fewer than two different parties are involved.
