Yeah it’s not fair to expect volunteers to show up on weekdays, I agree with you.
But equally, I don’t think it’s fair that packagers want to have it both ways. Packagers want to make subtle, possibly breaking changes to software they didn’t author. The end users feel the pain and complain to the author. The author has no control over the situation, and they’re feeling the pain during the working week.
So the packager has been instrumental in creating the problem with the patch, and when requested to do something about it, turns around and says “buddy I do this for free, I’ll get to it over the weekend, maybe.” Sure, but the author is feeling the pain right now.
Again, it’s nice that you’re volunteering your time for others. But it would be good if you acknowledged that the costs of packaging aren’t borne entirely by packagers. Authors bear part of the cost when they get blamed for broken software.
