There are plenty of companies that have paid products and still do user-hostile things including stalking, spam, dark patterns, etc.

I paid full price for a Playstation 4. I still had to opt out of "enhanced data collection" and spend 15 minutes disabling every option on their bullshit attempt at a social network. Even the games themselves had their own telemetry crap I needed to disable buried deep in some advanced settings.

Spotify still insists on ratting me out to Facebook by loading their SDK even if I'm paying for the app. They also interrupt my flow every so often with in-app popovers about some stupid feature I don't care about.

A client I worked for that has a paid app had an insane amount of analytics and marketing SDKs in the app (including Facebook of course), so much that I actually refused to install the app or use the product myself even though they gave me a voucher.
