It's been a year, and the story blossomed into a proper soap opera.
Esquire published a profile on Dan Price, portraying him as a greedy, pushy, obsessed publicity hound, given to exaggeration and self-promotion. In other words, a born CEO.
I don't think it's reasonable to conclude anything from the wage experiment, given the lawsuit, the circus of publicity surrounding the salary program, the allegations of spousal abuse, and the book deals. I don't know of any other CEOs that have followed Price's example, but if they do they can't count on getting presidential candidates to mention them, or media adoration that knows no limits.
