The only open-source product I use that might seem fun to contribute to is Home Assistant. All the other ones I use clearly have plans to monetize (n8n, Hermes, Linux, etc). So I'd just be giving free labor.
Why don't you contribute? Are you comfortable just taking from society?
Since an overwhelming number of open-source projects I use these days have some effort to monetize as part of them. I no don't feel it's free.
But outside of that, I feel I contribute in other ways and lack[ed] the skills to contribute to the projects.
Problem is, I live in a capitalistic hellhole that demands I be wildly profitable to someone else, least I suffer from starvation, destitution, homelessness, or even death.
