Twitter is another form of public speech, like interviews, public lectures, etc. Scientists always were accountable for re-interpretations of their lectures, public speeches. Why it should change on twitter?
Really? Tell me how scientists have been held responsible for reinterpretations. It's easy to find many examples of scientists who can't be blamed for how their discoveries are used. For instance, Watson and Crick would never have reported DNA because they knew it would be used by supremicists and other racists to justify their thoughts.
