"In my opinion that type of comment is worse than backseat driving" By that logic, I'd have to lease a mainframe for millions of dollars before critiquing aspects of their offering. Likewise, I'd have to pay Oracle $70,000 per processor. If flawed FOSS, I'd have to go through the pain of setting up and using it instead of submitting the flaw. Your analogy would apply better if you said "person in back seat shouting about an obstacle they're about to hit to driver that fell asleep." Realistically, though, better to critique than use flawed products unless it gets the job done enough to be worth using anyway. No need to become a stakeholder.
