I am happily paying money for email hosting so that my emails are not farmed for advertising. Have been with privacy respecting paid providers since 2015
I will happily pay money for instant messaging if the app respects my privacy and does not log metadata. I paid for Threema licenses, although I don't use the messenger on a daily basis.
I will happily pay money for ad-free privacy-respecting search results. I was using DuckDuckGo for years now, but just found out about kagi.com and am testing them now. Paying a small amount of money (over lightning) for unbiased well-indexed search results sounds well worth it!
All of these services cost a lot of money to host for the providers, and you know the saying: either you are paying for the product or you are the product.
