"Sure, but if you're terminated for cause you shouldn't receive anything."
This assumes that, for example, when he became an SVP, he was still on any sort of standard employee agreement.
That is highly unlikely.
Almost all execs at that level in that large a company would have a specially negotiated agreement. Most still end up with something even if terminated for cause.
Almost all their exits would be specifically negotiated mutual separation agreements.
(I'm not defending the above, obviously, just explaining what i expect is the case based on experience)
Also worth pointing out: don't know when he was made SVP/etc, but it probably predates any pushes to change any of this in tech. :(
