I guess I was making the assumption that "tech" businesses are more likely to have data that's entirely generated by modern software (e.g. click logs) or at least pre-coerced into a consistent, if not structured format (e.g. tweets), whereas non-tech businesses are more likely to have data that's free-form human input or comes disparate/arbitrary machine sources (e.g. scientific instruments, the mainframe or AS/400 worlds). I'm sure there's a spectrum, but my point was that the vast majority of what the companies we read about on this site ("tech") deal with is going to fall close to the consistent-format edge of the spectrum, hence the prejudice.
