Is that's what's happening here? The bit about suing her "even if the statements she is making are true" makes me think they're not trying to sue her via defamation, but through non-disparagement agreements. If that's the case, I'd hesitate to characterize this as SLAPP. If you voluntarily entered into a non-disparagement agreement and got something in exchange (eg. in exchange for severance or whatever), then at the very least it's slightly different than a journalist or whatever trying to expose some scandal.
