You're assuming you know better than millions who believe cheaper IS in their long term benefit. Quite a sweeping statement!
It is sad that some people in Silicon Valley find it acceptable and ethical.
It should be clear as day what’s being collected and it’s a failing that it’s not, but there’s also the old adage of “if it’s too good to be true...” doing some due diligence when you’re promised the services of a billion dollar company that’s not charging you is prudent.

Google asks devs how much an app costs to install not to use.
Even if the app has IAP the value gets rendered as “Free” with an additional notice.
On that note Google will also take down your app if it doesn’t have a comprehensive privacy policy. And it also requires that policy to be accessible without installing.
They’ve been cracking down on things as detailed as “leaking” clicked URL in troubleshooting logs.
I’m not here to astroturf for companies abusing jargon filled pages of legalese to get you to sign over rights to your data, but you don’t even need to read those to know: “If you’re not paying, you’re the product”. Doubly so if you’re using a service valued at billions of dollars.
The whole free versus pay argument is sophistry. Many pay products usurp your privacy. Your television is selling your viewing habits. Your car telematics solution is selling your movements. That operating system is mining your activity to sell you things.
And many free products defend your privacy. Linux, VLC, Firefox, IPF, and on and on. More concerned for your privacy than any other product.
So can we please stop this binary differentiation. It isn't useful.
