For context Heroku was created in 2008 just after the housing crash. By the time they exited Facebook was still 2.5 years away from going public and a solid seed round still looked like a few hundred grand if you were a hot company (on top of the ~17k you'd get from YC).

http://web.mit.edu/6.933/www/Fall2000/teradyne/clay.html: Even after correctly identifying potentially disruptive technologies, firms still must circumvent its hierarchy and bureaucracy that can stifle the free pursuit of creative ideas. Christensen suggests that firms need to provide experimental groups within the company a freer rein. "With a few exceptions, the only instances in which mainstream firms have successfully established a timely position in a disruptive technology were those in which the firms' managers set up an autonomous organization charged with building a new and independent business around the disruptive technology." This autonomous organization will then be able to choose the customers it answers to, choose how much profit it needs to make, and how to run its business.
If you can hold onto control of your company and take a few million off the table, why not?
No reason why this won't change. A market leader needs to consolidate their position year-after-year. GitHub was a great acquisition AWS missed. They shouldn't want to miss the next GitHub.
I just don’t see the valuations lining up, but I’ll probably be wrong.
I also don’t know who they get acquired by. I don’t see AWS making acquisitions like this. From what I’ve seen, it seems like they try to buy companies at lower valuations (than multiple billions).
