That's fundamentally a mischaracterization.

Everyone focused on short term gains. Optimizing for browser with 30% market share, backed by Google makes more sense than a browser with 20%. Repeat with 40% and 20% respectively. And so on, and so on.

There isn't a lesson to learn. It's just short term thinking.

Now Google has enough power and lacks scruples that would prevent it from exploiting.
