1. Because Amazon is a bigtech corp making a film about another bigtech corp. Plenty of conflicts of interest here (in either direction).

2. Regardless of whether it is or isn't related, implying they are without any evidence is just speculation. There's a reason they didn't say "months after" in the headline, even though it would be much more informative and much less confusing!

You also seem to conflate "there's evidence for" and "you believe that". Those are very distinct statements. "you don't believe there's evidence for X" doesn't make sense here — I said "there is no evidence for X in the article", that's a fact, not a belief.
