I specifically said in the article that it's not the takedown I had a problem with. But the total lack of support in solving the issues. If I'm not made aware of the rules, I can't fix anything. They specifically said I had to get back to the original complainant to get my app reinstated. That email address is a black hole. So there's nothing I can do.
I didn't say any of that.

I don't think Google or Apple could ever (or should ever) - in any meaningful way - advise you on copyright law. That would ultimately boil down to a civil issue between you and Facebook. Facebook, however, made it quite explicit what their issue was. By your article it seems you did not try to rectify the issues that Facebook brought. The notion that you exhausted all avenues to getting your extension re-activated is simply not true.
This is not a great defense. We know from the trail you presented that someone from FB's legal/compliance team found your extension, not the others, likely due to its visibility and popularity. That doesn't mean the other extensions are in the clear. It just means they weren't on FB's radar.
> The extension is free. There is no advertising. I don't make any profit.
I'm sorry, but that's irrelevant. The complaint wasn't that you were profiting from the ™, just that you were using it.
> If I don't know what I'm doing wrong, I can't fix it. This is not about TM infringement, but the total lack of communication by Google
I cannot disagree more. They told you what the problem was and the originating email explained that quite explicitly. You did not have permission to use the trademark Facebook (or FB). That's it. If you removed those protected trademarks, it would have been a different story.
