Wikipedia er et godt eksempel på en handelsfri tjeneste. De tilbyder en online encyklopædi og vil ikke have noget til gengæld. Jeg behøver ikke at give penge for at få adgang til Wikipedia, jeg behøver ikke at handle med mine data, opmærksomhed eller noget andet, da de ikke har nogen trackere eller annoncer. Af 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.

I think that’s the closest TF service as it can be, and it’s always one of the main examples. It’s collaborative, educative, and reliable resource used by the whole world. They don’t have ads, and also have a policy about NOT advertising. They run by donations.
