Are the people who made the promise even still at Google?

It reminds me of those sketchy companies on Amazon promising "lifetime guarantee" on their products when they know already they're gonna close shop and reopen on a completely different brand the very next year.

If those people made the promise on behalf of Google while working there and being in a position to make such promises, it's Google's problem now.

(If they _weren't_ in said position, it's still Google's problem but with some caveats provided Google actually treats it as abuse of authority.)
