I'm not sure why crypto news websites are spinning this news but it is most likely to create some noise and have some views for their website. CNBC have showed a different type of
article regarding this news and they have portrayed Tim Wu as not a critic not at least how cointelegraph has portrayed Tim Wu.
“Bitcoin may be in a bubble,” he wrote, “but it is part of a much bigger trend that is here to stay: a shift in trust from government to technology.”
Though bitcoin isn’t backed by any government or reserve asset, it “might work fine as a store of value that you can sell,” Wu also wrote.
For me with this kind of opinion I don't think you can clearly say that he is a critic comparing him to other people like Jamie Dimon saying negative things about Bitcoin what Wu said is far from those.
