I'm all for this. Unobtrusive and just enough to put it in folks mind. I'm not a big fan of the Author though.

How come there's no photos of the before/after? That would be much more useful than the condescension. They treat the reader like they've already whined with the least reasonable complaint. But they don't even bother to make their case properly, just point fingers at who else has done it, as if that's reason enough.

Wikipedia is NOT a good comparison. Their banners are obtrusive, obnoxious and the reason I stopped my $1/mo donation more than a decade ago. Well more specifically the begging/crying prompted me to look into their finances and spending and it turns out they were pretty irresponsible at least then. Lots of highly paid "administrators," software devs working on poorly thought out systems. Lots of interfering with volunteer contributions.
