I pay taxes. I pay for every park in my city. I pay for state and national parks too. I rarely/never use them. I have no choice. That makes me sad. I wish I could direct where my personal tax dollars were spent, but that kind of defeats the point of taxes, which are to fund the things that nobody wants to pay for (or are impractical to pay for, individually).

At what point did OP say, "you're only allowed to be sad if you contributed"?

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."

Yes, I can't finance every park. I can feel sad about people suffering throughout the world without personally supporting them all.
