I don’t think this is such a rare feature, though it’s generally not made obvious at least.
What I mean is I wish companies would send their transactional emails and newsletters in plaintext. Images and the like could be sent as attachments, as opposed to creepy weblinks that track your opens and IP and everything.
I would pay each company $0.10 if they offered me the option of receiving all their emails in plaintext like this.
And you'd also need to be able to somehow force them to <<only>> monetize you through direct payment, because what most companies do is, take your money <<and>> also sell your data, on top of that.
But this is hilariously false. Nowhere near “most” companies are selling your data.
In fact, an overwhelmingly vast majority of all businesses don’t sell your data. This is true inside Silicon Valley and even more true outside of the Valley.
Even in Silicon Valley, most companies understand that selling products and services to customers is more profitable than trashing a customer relationship by selling a customer’s personal info to third parties.
I think people use 'selling my data' as an (inaccurate, sure) shorthand for 'collecting so much data about me and I don't really trust them not to sell it at some point'.
That's because they haven't figured out how to. Or at least how to do it to make it worthwhile.
Secondly, we're all doomed. I recently read an article about Amazon's ad division being as big as AWS and growing as fast, if not faster:

If even AWS isn't bigger and isn't growing faster than ads, what hope is there, really, for someone trying to just sell stuff?
