And the ones that stay behind will be the kinds of teammates nobody wants to work with.
Google is already falling behind in pretty much every area where they have competition and getting sued in all the areas where they have driven the competition out. It will really be great to see their business shrink given what they have become in the 2010s.
On the other hand, it's also really sad to see what they've become too. They used to be a really admirable company around the early 2000s. So many people were cheering for them as a company run by engineers, doing things differently and running all over the incumbent assholes everybody hated like Microsoft. There was a time when it felt like Google was a company for real people fighting back against the machine. But then they became the machine themselves.
The good Google is dead. I'd love to see them get completely buried.
Of course developers wanted this. They wanted to push all the complexity into the browser so they didn't have to worry about it themselves. Google was happy to provide this because it meant that they could be the only ones that could write a browser. That was the "conspiracy" you're talking about - but it wasn't a conspiracy, it was more of a strategy on behalf of Google, who knew that they were the only ones that could provide this level of support, and so if they did it, nobody else would be able to compete with them. Even Microsoft gave up on their own engine.
But the only reason Google could do this is because they were deriving revenue from their advertising monopoly. If their web browser was honestly funded, many, many of the features that we see in Chrome today would have never existed.
