IPOs are a really tough path, and can significantly alter the business. I'd hesitate to hold up the big one for this year as vindication for her entire approach. The vast majority of growth tech companies are not going to go public, but need to release value for investors and employees, and PE or acquisition is the only path open to them. If you've ever had experience with PE you might not want to deal with that, and getting bought is all that's left if you owe people a big return soon.
Sure, and a counter-argument of the form "acquisitions from such valuation to such valuation were down such percent, we interviewed the following founders and these Corp Dev lawyers spoke on the condition of anonymity..." would be an interesting one. But AFAICT at everything but Goliath scale, M&A was actually up over the period.
So as usual here we are with the epic showdown of Data and Vibes...and in an obvious landslide Vibes takes it home.
