The funny thing is that this is essentially a giant ad for this person's business, and their website uses GA (lol). I've noticed this is an increasingly popular tactic on Reddit and HN. You clickbait people to an article backed with no data that you know will tickle people's emotions. Then at the end you include a call to action to use their service because it will save the world.
I used to hate GA as well as ads in general when I had never tried to start my own business. I had the typical Reddit/HN anti-FB-and-Goog mindset. After trying to start one, I completely changed my mind. I couldn't find a reliable way to put my site in front of customers without ads. I guess if you're popular and have a huge social media reach that might be enough, but for someone with no social media presence it can be tough.
Once you start spending in ads as a small business, it's useful to have some data to understand what the hell is happening to all that money. I spent thousands on FB, Google, and Reddit ads and it's extremely difficult to find out what is happening and which ones are working. How do you know which people are coming from which ad? Which ones are real people vs bots?
I strongly recommend people try to make a website/app without being popular on social media and try to get people to use it without using ads. Places like Reddit are generally against self-promotion. If you Tweet/post into the ether of Twitter/FB no one is going to randomly see your post. After using ads, I've started to pay closer attention to ads instead of instantly ignoring them. It turns out that they are frequently useful. For example the other day I was searching for services for hiring a remote contractor and the ads were more relevant than the search results.
As for this article, I don't really follow the logic. A lot of it seems to be backed by the knee-jerk emotional hate people have for powerful companies. For instance, when talking about how Google uses GA:
> we don’t even need to speculate. It seems pretty obvious to me that they’re using it to guzzle up even more data and to crap out ever more gold ingots.
Every time I see the word obvious, that is a sign that a big leap of non-obvious logic has been taken. It is not obvious that GA is being used for bad things, maybe Google just makes a ton of money because their products are useful. The rest of it also seems mostly backed by emotion. I guess these type of emotional anti-big-tech articles are quite popular here though. It seems like every day there is a new one.
