It's impossible for everyone to change their behaviour, because that's too many people. Some people are just assholes and don't care. Or they're idiots and don't understand. Nothing we can do about that. Most people are alright, but with 8 billion people on the planet even a small percentage being an asshole means a lot of assholes.

For the most part, the people who care already care (you, me, most others commenting here) are not really the problem.

So ultimately the only thing you can do as a maintainer is set your own boundaries for yourself. And the original message in that thread ("there is no activity, what are your plans?") is a fair question, although the follow-ups are not.

All of this is true for a lot of the internet by the way. The best thing of the internet is that anyone on the planet can talk to anyone else on the planet. When I was a kid I did some ham radio with scouting, and you could talk to people from places like Russia and the US. Wow!

The worst thing of the internet is that anyone on the planet can talk to anyone else on the planet. You're constantly exposed to a seemingly never-ending stream of assholes and idiots, and a single asshole can ruin the day of dozens, hundreds, or even thousands of people every day. Maybe this is just 1% of people, but 1% of 8 billion is 80 million.
