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.

Creo que ese é o servizo de TF máis próximo que pode ser, e sempre é un dos exemplos principais. É un recurso colaborativo, educativo e fiable usado por todo o mundo. Non teñen anuncios e tamén teñen unha política sobre NON publicidade. Funcionan por doazóns.
