Till Gabe dies and valve is bought out by private equity

Imagine if Gabe went the Yvon Chouinard way? (founder of Patagonia refused to IPO, never sold controlling stake, recently left the entire company to an environmental conservation trust - certified LEGEND)

Gabe seems like the kinda guy who is in the Game for the love of games.

It would be a legendary legacy indeed to commit Valve and it's profits to a trust which defends digital rights and freedom.
