Even with evidence a logical conclusion can still a supposition (aka an uncertain belief), and often is in the face of the kind of information asymmetry inherent to any outsider commenting on a private company's internal roadmap... but I digress.

My point is simply that is we can skip the passive aggressiveness and just say "can you give me some more evidence that would help me reach the same conclusions you've reached".

Otherwise you're not actually asking for a source, you're just saying "I disagree" in a very roundabout way.
