At risk of derailing this conversation, but a common problem today is that oftentimes the companies offering a free service simply won't let you pay for it: long before Elon and Twitter Blue, I wanted to pay for Twitter so I could have an ad-free experience with some kind of "personal-grade" API access so I could use my own clients - but that was never an option.
Similarly, I would like to pay Google for an ad-free search experience (and to filter out content-farm websites from my search results...), instead Google's attitude is pushing me towards https://kagi.com/ - which is their loss, I suppose.
There's also the worst-of-both-worlds: when you pay for something, and it still comes with ads, and introduces user-hostile changes to the UX - or otherwise leaves you with the feeling that you aren't valued as a customer (e.g. Windows 11, Reddit, post-Elon Twitter, etc).

We're told that as customers in a free-market it's up to us to vote with our wallets, but clearly even that isn't working to effect the change we want to see.
