The one quantitative thing I think you can say about companies with lots of remote workers is that they don't have to pay as much for engineers. Speaking as someone who lives in the Bay Area, that makes me less likely to work for such a company. Yes, I could move somewhere where the cost of living is lower, but I actually like it here, and I have yet to run across a company with a strong remote culture that doesn't use it as a cost-savings device (among other things).
