Why would a company conduct a survey for internal use that they intentionally flaw? If a company is wanting to see how a change would influence their market, they'd want it to be as accurate as possible. I could maybe see a biased poll or survey if it was going to be released to the public, but it makes no sense if they're doing it for internal use.
It's like if you went to the doctor and paid him just to say everything is fine instead of actually having him tell you what's actually happening and how to fix it.
Two MAGICAL!!! PR words: "Guest request".
