What it means is that the Google mindset of introducing and later killing off whatever services they feel like, extends to how they view the standards process, viz. that it’s theirs to tinker and butcher as well, and coupled to that the implicit belief that their implementation of the web is the reference implementation, and the rest of us simply subordinate to Google’s commercial preferences. Other vendors do this too - the fundamental conceit at play is as old as the tech sector - but that doesn’t make it any less arrogant or reprehensible behaviour. With that understanding, the process note above from an ex-Google employee amounts to a description of wilful abuse of market power.
