Another data point. When Musk bought twitter and started wrecking it, several people I followed created an account on blue sky but most did not use it that much. This seems to have changed over the past week (i.e. after the US election). Dozens of users have moved, pro-Ukraine people in particular. Some double post. As certain content creators move, others do the same, amplifying the trend. It's interesting to see network effects at play.
