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.

我认为这是最接近的 TF 服务，而且它始终是主要示例之一。它是全世界都在使用的协作性、教育性和可靠的资源。他们没有广告，也有不做广告的政策。他们靠捐款运作。
