> what is the relationship of your analogy to this situation? is the maintainer the homeless person in your analogy?

It's your analogy, you tell me.

> you can criticize all you want as an exercise of your critical thinking faculties but the volunteer is not in anyway obligated to heed the criticism.

Nobody said they were. Nobody's trying to punish the maintainer legally. That doesn't mean criticism won't be offered or warranted.

Here's another analogy: You have a right to be a jerk in real life. Nobody's going to physically or legally stop you, barring extreme circumstances. People will still criticize you for being a jerk, as is THEIR right.
