We know it's not evil - it's just business. However, plenty of businesses are built around anti-consumer practices.
I personally don't mind someone tracking me on their own domain. Javascript trackers are terrible for security and performance reasons, though I'd tolerate them. I don't like 3rd-party trackers, though, for many reasons:
1. Part of the selling point of using those third-party trackers is being able to quantify what type of user/consumer I am. That's why they track across multiple sites - to provide their customers the highest value. So that they can charge a higher per-unit price.
2. There's no guarantee that such data is only shared with the sites accessed. Even if it was made at the point of use, they can retroactively change that without contacting the user because its their customer who signs the agreement. Most will just click yes without thinking of their user's privacy.
3. If the business sells, merges, changes leadership or goes bankrupt that data policy is as worthless as your trust in it. Look at RadioShack's attempt to sell customer data despite promises not to. Or any company who changed their TOS after a buyout. They don't wipe data from people who don't agree because that data is part of the "company value".
I admit that GA makes a lot of site maintenance and analysis easy. However, I'm not particularly interested in making your job of selling to people easier at my own expense. Particularly when alternatives exist for people who know what they're doing. Yes, it's not malicious behavior, no, but it is extremely discourteous and occasionally sensitive to disclose interest to a third-party.
Think about it like this. Let's say I go to a dealership to look at cars because I like looking at cars. I love engines and wheels and stuff. I only speak with the sales guy, who really seems like a pretty nice person. But the company contracts with some guy who is watching me the entire time for "analytics". After I leave, he tells my bank, the IRS, my wife, my boss and my cousin who asked me to loan him money (but I sensibly declined because he never pays anyone back) because they know him and this guy can't and won't keep his mouth shut. The next day, my bank preemptively reviews my credit history for a car loan, I'm being contacted for an audit out of suspicions of hiding money, my wife is asking me to buy her something because we've apparently got money, and my cousin is livid that I'm somehow filthy rich but I won't give him $10K to invest in a critical MLM deal. It's his big ticket and he'll have it back to me in 3 weeks. Well, 2 months, tops.
Your intentions don't matter at all with 3rd-party analytics because that 3rd party will never respect those intentions. It's not in their contract and thus not their concern what you intend or promise. Plus, their lawyers regularly update it when the company finds new business models to exploit. Not only that, you don't care enough about me to actively review your vendor contracts to make sure your "good intentions" are being followed by your contractors. You're only using the service because it makes your job easier. Why would you go out of your way to do extra work? You don't have any bad intentions, after all.
It doesn't have to be evil or malicious to be exploitative. It's not like third-world factories with terrible labor conditions exist because the owner likes to kick puppies. It's about money, at the end, and businesses will do as much as they can get away with for money.
