Valve kinda shows how a well-managed private business ought to run: respect your customers, find a cash cow and use it for slowly expand into related markets to your niche, develop good products over a long period (SteamOS took many years to become something actually useful) without focusing on the mentality of hyper-growth, keep the stereotypical contemporary MBA thinking away, have a small but competent team.
There are, of course, the issues with lootboxes but even there they've kept their hands much cleaner than any other game developer.
It's a very well oiled machine, I had another VR headset ordered for sim racing, immediately canceled it when saw the Frame announcement because even if specs-wise it's a bit of a downgrade, I want to buy what Valve is selling.
