I would be careful with trusting the answers to those questions.
People remember things to be more positive than they were. This is an established bias in human psychology

Fair point; to correct for this bias, ask n people to rate their experience with software reliability, then wait five years and do it again. The larger your n, the more you correct for individual variation (via the Law of Large Numbers)

1) Asking five years apart only confirms if the bias is stable/changing. It doesn’t correct anything.
2) Asking more people gives you an answer closer to the ‘truth’ (i.e. the true population mean; the mean answer if you asked ‘everyone’). It lowers sample error, not directional bias.

I read your response as “okay then, if we can’t ask that question, we have to spy” etc. which I think did not follow from my post - I misunderstood you, thanks for clarifying.
