Well done, Andrew! You've written a an article that slates Google for exactly the reasons they need to be slated without resorting to double-standards, broken logic chains or smug insinuations.
And you're entirely correct, this is one of the many valid axes to grind against Google, they're the single biggest contributor to the internet becoming a festering pile of ad-funded idiocy with every single element being relentlessly monetised in the insane ephemeral shell-game that is advertising.
It's not just about their dominance in advertising but in the way that their (and Facebook's) success has let to a narrow view of the internet where every spare pixel is strip-mined for ad space while simultaneously stalking the entire population of the planet with an obsessive level of creepy attention that would make Jeffrey Dahmer shudder.
And on the back of their gaming of tax systems, underhand lobbying and bullshit proselytising they've given rise to the magical thinking of profitless companies being worth billions and the "sharing economy" sleight of hand that allows the likes of Uber to try and avoid all aspects of regulation and consumer protection while swallowing cash and claiming they're in some way benefiting someone other than themselves. I used to think estate agents were the very worst kind of middlemen until the rise of the "but we're just a platform" parasites.
Anyway, more like this Mr Orlowski. Nail them for the things they do that are terrible, not just everything they do because you don't like them. I don't like them either, but stick to the facts and hang them with their own (ad-sponsored) rope.
