I suspect they gave him a timeline to IPO and/or sell or he's kicked out as CEO. His recent actions are those of a man with a deadline and nothing to lose.
Assuming that is the case: WordPress the company only needs to stay stable and valuable until everything goes through; if it burns down after that he's still met his obligations (to an extent).
If you invest in a company and it’s valued at $1,000,000. And you want to make some money. You sell your investment in the company.
If after 5 years revenue doesn’t grow the value is still $1,000,000. Unless the value increases the investors won’t get a return on their investment. Often investment comes with conditions.
So no it’s not as simple as “just needs to stay stable”
