How does one withdraw what has done years prior?

Is this a hand slap or would it have legal significance?

[Freedom of Speech Wins]

I don’t get that either.

There is no legal significance, or to the extent there is, it amounts to erasing the trail of malfeasance.

All warrants expire. The warrants are basically time-limited licenses from the courts to snoop, and any evidence obtained will be admissible in trial. This is asinine because virtually no FISA-obtained evidence sees the light of day in a courtroom. The entire process is secret permission to conduct secret snooping, with the goal being to deny that the snooping is taking place.

The FISA system is a variation of punishment by process, except the punishment is being surveilled so the government actors gain whatever personal advantage attaches to that, for them.

Using the "fruit of the poison tree" doctrine, it might have significance.
