The Google logo bugged me the first time I booted the phone with GOS and it appeared, even though I knew it would.

Then I didn't mind it.

Now it gives me immense satisfaction to see it coming up and then being replaced by the GrapheneOS logo.
It feels like a victory every time. Like vengeance even!

I feel the same when the "you are loading a different operating system" screen shows up, that's right! Just how I like it.
