It's not that people are ungrateful or some bullshit like that. It's that nobody's announced that this mangaka has had freaking HEART SURGERY (allegedly. That's what I was told, anyway.)
5 months of no chapters for no reasons is head scratching. 5 months of no chapters because surgery is completely understandable. Don't get upset about people who weren't told the full story. Just spread the truth. The mangaka had health problems and took a break.
