Alright, take a park closing then. Can you be sad about that if you haven't personally raised money to finance the park?
OP pointed out that many people stated they were sad. OP also pointed out it's likely few of those who were sad also contributed money. For a project whose maintainer said, essentially, "I can't keep doing this for free," the connection for most is obvious: "we (individuals and corporations) need to keep paying for the things we use and love if we want to keep the things we use and love."
OP did not say, "don't complain to me if you didn't personally try to save it."
