Wikipedia is a great example of a trade-free service. They offer an online encyclopedia and don’t want anything in return. I don’t have to give money to access Wikipedia, I don’t have to trade my data, attention or anything else, since they have no trackers or ads. Of course they need money to sustain themselves in this trade-based world, but they make this voluntary in the form of donations. So if you can and want to support them, you can do so, if not, then you don’t have to – you will still have access to Wikipedia.

我認為這是最接近的 TF 服務，而且它始終是主要範例之一。它是全世界都在使用的協作性、教育性和可靠的資源。他們沒有廣告，也有不做廣告的政策。他們靠捐款運作。
