Olden days being FB and Twitter APIs? Don't forget about Apple Sherlocking independent devs. This has been happening with almost any platform for a very long time.

Back in the day, a contract company I worked for had entire teams of people dedicated to building FB apps. When that collapsed, it came down fast and hard.

Still true today for AWS.

even before that, by some accounts I hear the reason VCs over invested in dot com was primarily because they saw something that could not easily usurped by Microsoft by releasing their own sh*tty copy. so they all piled in and then bubble dynamics took over.

story as old as internet itself!

don’t forget m$ as well.
