This is something that programmers (including myself) are often guilty of. We see an implementation and understand what features based on that implementation are difficult/infeasible. Then we say things like "it isn't possible with our architecture" and "It is understandable that the website works in $x way."

The flipside is true too: developers are very understanding of bugs/shortcomings that are borne out of the specific implementation. With all this knowledge, it is easy to say things like "people shouldn't use this tool for that" or "users should know this is flaky"

At some point you have to fight for the user instead of defend the code.

No, I suppose my point was more that people think that one of the features of Google search results is correctness, which is false. The main feature of Google searches is that it shows you what it thinks you want to see.

The "product" here is the fast search engine that indexes a massive portion of all human knowledge and tries to provide you with results that are meaningful to you all within a quarter of a second. I don't think it is broken, I think it is a miracle that it works as well as it does.

Unfortunately, there is no algorithm to determine "the truth", mainly because there is no universal truth. This is a feature of the world we live in, though I suppose you could call it a bug if you think that there should be some kind of universal truth.

If nearly all of your users believe that your product delivers X, when it actually delivers Y, then your product is still broken.

No, your product is not broken. You have a marketing problem. You sold your product as something it was not and now you pay the price of lying to all your users.

I bought a car, when I turn the steering wheel left, the wheels turn right. Damn marketing!!!

More like, "This piece of software I don't understand did something I was not expecting, so now I'm upset that the software isn't actually what I thought it was and I want it changed".

If your software is actively presenting something as X, when it's actually Y, that's not a marketing issue. That's your software displaying erroneous data. That's a bug.

There is explicit marketing and implied (historical, metaphorical, etc) behavior.
