I vaguely recall hearing that his son had no interest in running the company but that was also years ago. Hopefully whoever is set to take over when he goes shares his exact same views on keeping the company private.
I think if he really wants that plan to shake out he needs to transition ownership while he's alive. Just dumping it on them with no discussion, no cultural adjustment and no preparation time will cause a lot of problems.
And this is why we shouldn’t rely on steam to be the one and only saviour. GoG and pirating is needed so we can make sure we can enjoy our games in the future.
I don't think Gabe has any interest in that. He's so filthy rich, at this point everything is just a hobby paid from change he found under a couch cushion.
