Giving it some more thought... I suspect that Musk would whine about a conspiracy but refrain from encouraging obstruction of justice. People like Musk would probably benefit from Trump being arrested -- they could milk the resentment of his arrest, while getting Trump out of the way for them to insert people closer to them.
For the broader Twitter community, I suspect that Twitter does not have the administrative capabilities to handle a flood of incitement to criminal activity, particularly after Musk's shakeup/downsizing.
