Yeah I don't disagree that the U.S. has been selling technology that can be used for nefarious purposes to not nice people/outright bad regimes for a long time,

Yeah I don't disagree that the U.S. has been selling technology that can be used for nefarious purposes to not nice people/outright bad regimes for a long time, I think the reason why people are concerned about this is because China has an even more negative track record (at least recently) for human rights, mass surveillance, etc. and ostensibly has fewer demands for the people it sells to to be more Democratic or use the technology in non-authoritarian ways
