The internet makes it harder to determine the truth. If not careful, then anyone can start spreading falsehoods against their best intentions. Nobody wants you to shut up about the truth, but your ability to judge what is "true" is greatly impaired by the cheap (and legal) proliferation of falsehoods.
I am impatient with this type of argument. Falsehoods proliferated just fine before the Internet; truth seems a more fragile flower. I think we've got a net positive.
