I'm also not a statistician. The assumption you're making is that the
people who opt-in would be a representative sample of the whole
population, and I think this is quite plainly not true. I think there's
a high risk of sampling bias causing skewed results. There just needs to
be some link between people who tend to opt-in and the sort of hardware
they tend to have that is different from the general population, for
example, to end up with a skewed sample.
