"The Board has done its main job - changed the CEO."

Victoria explicitly referred to the Knowledge Equity Fund in that post, which appears to have been Uzzell's and Maher's brainchild.
The Knowledge Equity Fund became very controversial last year when people realised it was set up to funnel millions of dollars of Wikipedia donations to non-Wikimedia social justice causes via Tides Advocacy:

Janeen announced on 14 May 2021, two weeks after Katherine had left, that she was going to leave the WMF and devote herself to racial equity and technology causes:

She started as CEO of the National Society of Black Engineers on 7 July 2021, just one week after her last day with the WMF.
Including the $325K severance, she pocketed over half a million dollars for half a year's work and went straight to her next job.
Frequently these types of severance packages are to make up some sort of assumed bonus and ensure no compensation based contract disputes later.
But generally yes, if much of your compensation is bonus based most executive contracts will have a mechanism for pro-rating or just paying out future bonuses.
This sounds a bit like it was something of a mutual parting of the ways so sometimes boards will payout other bonuses like Retention Bonuses (A bonus for staying at a position, frequently with another job offer at hand) even though the person is leaving. It could also just be a bonus triggered by the board choosing to part ways with her that was part of her executive contract. Proving a firing is "for cause" is frequently difficult so sometimes if there's a desire to replace a senior executive it's easier to just pay them off.
