Do you regularly pay for any privacy-enhancing tools?

I do pay for my email provider and support Signal with a monthly donation. I also run a lot of digital infrastructure myself on my own servers at home and I’m paying rent for some virtual private servers in a data center. Free services that are not supported by donations are always “bait”. At best, they exist to allow people to try a service and pay when they start relying on it; at worst, they turn the user into the product or combine both revenue models. The question “should service X be free“ is a naive question. For any service somebody has to pay. The only question is: Who and how?
