I find that my stance on this topic has changed as I have more money to pay for services. I used to vastly prefer free services. Now I would happily pay a few dollars. Unfortunately, a large portion of my privacy and anonymity has already been given up from past use of these free services, and I most likely will never be able to reclaim that. I can at any point choose to use a less invasive service, but the choice is not the same now that I view much of my anonymity already gone.
