I engaged with the folks pushing this feature internally when my own browser started enforcing omnidirectional login. One of my specific complaints was that it was an end-run around the user-provided sync passphrase, which nominally prevents Google from hoovering up my logged-out history. They didn't grok my privacy issue. Maybe they were deliberately misunderstanding me. Doesn't matter either way. Now I use Firefox.
Google's culture breeds internal arrogance and blindness to outside concerns. Arguing with Google people about issues with their products is approximately as effective as arguing with a brick wall.
I could imagine a high-flying company having entitled employees, I just don't see the qualitative difference between this or that company. Please enlighten me if I'm missing the point.
And lest I sound arrogant myself: I once worked in Pharma and made my peace with the price vs R&D logic.
