It (the review) only concerns actual product features. No political slant, no revenge, etc. It's 100% a product review and nothing else.
Imagine test-driving two cars. On the first, a wheel falls off as you round a corner. Obviously you aren't going to buy it, but then by your logic - not having bought it - you aren't allowed to comment on it.
Also, do you really believe that someone is going to be okay with a product they buy refusing to function, just because it's a tech device? Replacing consumables, even if the consumable is high-tech, is something that even non-techies can understand. As proof, I couldn't fabricate my own tires but would be annoyed if my car wouldn't run with 3rd-party tires, despite not being a mechanic. It's rude and sociopathic, to assume others are too stupid to come to the same conclusions.
