Depending on what you mean by support, when one of my youtube videos was falsely copyright claimed, I disputed it and the claim was removed. When another video was falsely flagged as violating a rule, I disputed it and the flag was removed. When someone started repeatedly stealing my videos and uploading them to their own channels, I reported them for copyright infringement, and the first time it took 1 day to be taken down, subsequent claims only took 30 minutes for the takedown.

Exactly, they handle things they are legally required to.

I'm pretty sure they were not legally required to unflag either of my videos.

Sure. They replaced my defective Nexus 4 quickly and with zero fuss.

Well, that's actually not google support...

Actually, it could be. If the phone was bought from the Google store, they serve you directly. I had my Nexus 5X replaced after a conversation with Google (not LG).

They provide much better support than LG regarding replacement of the Nexus 5X for bootlooping issues. Project Fi support has been pretty accessible.

there are a few, but it usually turns out that the person had contacts at Google or were a high profile blogger or something.

ordinary folks? Forget it.
