Leadership roles, especially in large corporations, often favor people who are opportunistic. They don’t care about the product, they want that promo.

And to win that promo you have to ship big and ship fast. So often times what you see is people delivering vaporware that has the appearance of high quality (lots of promises, looks amazing in the slides deck, carefully selected data shows great numbers, etc). It’s a gamble, and sometimes it pays off.

By the time people accept that it’s hot garbage, the leaders have already moved on to the next opportunity. And it’s not that they were able to fool their managers, because their managers are playing the same game on an even larger scale, so they care even less.

Of course, this is not always the case. But there is a bias, and it tends to show up more in large organizations (government, large corporations, etc.)
