Given the widespread use of "A/B testing" and targeted/algorithmic ads/UX/content, I don't understand why anyone would expect consistent behavior from any software. Unless you have matching SHA-256 hashes, the default heuristic should be to assume that you might have a "customized"/testing variation of the software. We really need to get in the habit of including hashes when talking about software behavior.
