Pure speculation...I've worked as a CS Rep & Supervisor. Burnout is a very real, serious event.
Being in that position, one is caught between pleasing the one who cuts the paychecks at the company, and the customers who spend their $$$ so those paychecks do not bounce.
The Internet makes it far too easy for unthinking/uncaring people to post nasty diatribes directed at individuals. The target was glued to Pizza's back and he took a lot of shots the past few months.
It's possible Pizza moved into a different department within WGT. I've seen that happen many times. Similar to a doctor with a practice moving into research. Not the best analogy, but ya'll get my meaning, I hope.
Personally, I hope he puts WGT in his rear view mirror and finds some peace.
To borrow a phrase from a dear friend:
Traveling mercies, Pizza.
