David Moyes was appointed as the Croatian's replacement on a six month contract.
While there was understandable apathy from fans to Moyes' appointment they have backed the manager from the off but questioned why Sullivan and Gold only offered a short-term contract if they felt he was the right man to take the club on.
And that short-termism could come back to bite the owners if Moyes continues to make the kind of improvements which saw West Ham turn in their best performance for 18 months when they beat Chelsea 1-0 last time out.
As proved in recent years West Ham have struggled to attract top managers during Sullivan and Gold's tenure.
Bilic was third choice behind Rafa Benitez and Unai Emery while reports claim as many as six managers were approached before Moyes was appointed last month.
If the Scotsman gets the Hammers upwardly mobile he could be in demand come the summer.
The club has a two-year option in the deal but given the toxic atmosphere between supporters and the board the former Manchester United boss may choose to cash in his chips while his stock is high at a club with more harmony and ambition.
That would leave West Ham searching for a third manager in just over six months and yet more upheaval on the horizon.
