I suspect this is a result of acquisitions.

They buy some startup, bring them all under Meta's HR umbrella with all the rules and perks that comes with. Since these recently acquired guys are running out of random offices in random places they just give them a stipend rather than force them to all relocate to a campus with dining.

The $400k employee was probably a higher up (or key SME Meta felt they needed to put in golden handcuffs) at one of these acquired companies and was probably already on his or her way out.

At Meta, $400k would be high E4 or low E5. That’s someone earlier in their career who probably feels fairly anonymous and is used to taking all the deals they can get to live cheaply, even if they don’t need to anymore.
