Fine with me. At this point I'd pay regular price plus the expected discount from data collection, just to be sure. Call it a "privacy fee" and I won't even be mad.
IMO the better question is when data becomes too expensive to be worth it.
There are currently no serious financial downsides to scraping, hoarding, selling, or leaking customer data. There is huge financial upside to doing or risking all of those things.
Companies' data policies may be user-hostile, but they're economically rational.
Data becomes "worthless" when the average joe's phone number is worth $0.003 to marketers, but there's a $500 fine for leaking it, allowing access from an internal team for purposes not specified in a granular opt-in form, or for being found to possess it after its deletion was requested. Routine third party audits are mandatory if you want to interact with other serious players in your industry.
For all the ways that banking and healthcare are hellish, they've at least got the semblance of teeth on stuff like this.
We'll know it's working right when companies spend the same effort to avoid hosting your data that they spend on collecting it today.
