I don't see why Twitter has to do it? If it wants people to switch political affiliations then this is the worst way to go about it. I know Jack Dorsey admitted that he is a leftist and most employees in Twitter are leftists too [1]. That those employees who lean towards the right feel threatened to voice their opinions within Twitter. If that is the situation within the company then how can you expect it to not be biased when dealing with political issues on the platform? Surely those biases will permeate into decision making. And one can't blame algorithms always. I don't see leftist accounts being banned by Twitter no matter how much hate and abuse you find on such accounts. So it is not automation. This is definitely targeted.
