I expect the amount of effort it would take to find someone who could do something about it is more than it's worth.

I've reported bugs in Google products before, but it's usually just not worth chasing a company down for something that doesn't really impact me, and often they'll just refuse to acknowledge the problem or refuse to fix it anyway. E.g. the issue I described at https://news.ycombinator.com/item?id=10478264. Since then I usually won't bother unless it's hard to work-around or the company has a known bug-tracker.
