I'm not into the analytics business, but how does it come that, somehow, of all the major tech companies, it just happens to be Google to provide the one irreplaceable analytics service? In particular, how that apparently never worried anyone before they became the "seriously nothing else can scratch this itch" quality analytics?? Because I saw it happen and it worried me. Some people must remember, about a decade (!!) ago, that half-joking nervous realisation that there was a single corporation whose server-controlled javascript ran on 90% of all webpages. Or the part where you share all of your site's analytics with a third party you had no choice in? That wasn't even a thing before GA came around. What is Google Analytics doing that it can't be replaced by anything that's not quite as ruthless with your visitor's data? (I really want to ask "is it that hard?" but I'm gonna assume there's something hard about it that I'm not thinking of) Personally I'm afraid the reasons are dumb and shameful. I suppose Google Analytics is providing some additional details and data that it just happens to be unable to provide unless it tracks the everloving shit out of your visitors and accumulates this data on, say, Google servers. And people don't want to give that up, because weeeeell if it's spying on everybody and combining and keeping data anyway, they might as well get a slice of that pie, right? Flawed reasoning that work very well in unscrupulous people's heads. And then you get someone complaining that the UX of the alternative isn't top notch. Which really tells you everything you need to know someone is willing to even begin thinking about sticking out a limb for. I get this sinking feeling that in large parts of this industry there's less than 5% of people who actually think about and critically look at the ethics of what THEY are building, and they're probably listened to even less. It's probably even less, I've been talking to people that I consider very responsible engineers whose principles just wither as soon as you ask where the analytics data goes ... usually pointing at the client's choice. Except they're working on it and it's built into the infrastructure of the company and they provide it. So easy to get the top thread in this comment section arguing fervently against any and all forms of tracking ... and then you get this massive back peddling when someone dares to suggest not using GA.
