"serfs were peasants who were bound to the land they worked on and were under the authority of the landowners or lords"

Last time I checked Twitter (the supposed lord) doesn't have the power to make you (the supposed serf) post on Twitter.

That is, I would say, a crucial distinction that makes the serf comparison ultra ridiculous.

Then again if Varoufakis said that the relationship between Twitter and its users is based on mutual benefit but Twitter gets more benefit, then it wouldn't make you as angry as saying that they people are serfs of techno-feudalists.
