You can rest assured a company firing you for what they saw while surveilling your work computer will not be so stupid as to reveil this fact. That would indeed be a liability for them. They will simply invent a different reason for firing.

Because they know it's not allowed (or at least frowned upon), but they decided to do it anyways, the company surveillance is kept secret and downplayed and plausibly denied as much as possible.

Or they just find another way to show you did it - the idea is very similar to how law enforcement uses illegal spying. They simply find another way to prove what they already caught you doing - it’s called Parallel Reconstruction.

Well, usually they would never tell the person the real reason for the firing or layoff anyways. there's no benefit for them to tell you, it just increases liability.

Telling people the reason is also likely to provoke an argument, which is often heated, and may become violent.
