This question has always been weird to me, but apparently there are people who don’t experience “this thing is good, i wish to contribute” or “this has brought me joy, i wish to give something back”. I mean, thankfully there are still enough others that we can have Wikipedia, where you also don’t get anything in return. Not even “clout”. Sometimes someone will send you a thank you and that’ll make your day. Open Source is another obvious one, but it extends to the real world, too. Some people will plant flowers in public places or do yarnbombing or pick up trash in the neighborhood or whatever. Why do it? What do you get out of it? I mean, I don’t want to be harsh saying “what a dumb question”, but it just kind of makes me uncomfortable how it challenges something that should be celebrated.
The next question about it being invasive is good and valid, but this one on its own just sounds like “why not content yourself with passively consuming”. I’m glad he called himself “generous” because it’s true.
