This is why I'm building free "spite apps" in homage to Larry David's spite stores [0]. The goal being to push back on enshitification of tech and dark patterns like mandatory subscriptions, ads and user data tracking.

As a solo indie-dev, writing free software (as in you don't need to pay anything) is fine, but I usually do not make the project (entirely) open source due to the added churn & maintenance.

In my experience, setting expectations early in my apps ("I'm a solo indie dev", "this is a free app", "you can reach out to me through email but don't expect super quick responses") helped reduce entitled users and - quite the opposite - people were super happy to get replies from me solving their problems.
