Yeah, look at the insanity in Chrome. It is open source but that's just the lip service. I want Google nowhere near my home gadgets. It might play a docile role and then eventually devour the entire project with funds/influence.
Chrome’s popularity dwarfs any other project by a factor of like a million.
Getting enamored by OSS virtue signaling is how Big Tech rules the world.
I'm sure there are many valid reasons to be critical of Google's business ethics, but keeping an important project like this almost entirely open source surely is not one of them.
Android, on the other hand, is a different case, with Google moving more and more basic functionality into the proprietary Play Services and proprietary apps.
