I doubt anyone criticizing is doing so because of "How dare they want money?"
Which just begs the question, why did you think that? That take just exposes a complete missing of the point of open source software and why (honest) people invest their time in it.
There are others who just want the caché and benefits that come with producing open source, but without the annoying actually being open source parts.
If you want to get paid for renting out copies of software, just do that honestly. If you want to make the world a better place and pay it forward for all the free stuff you were given, then do that honestly.
But wanting the benefits of sainthood without having to volunteer at the soup kitchen, no, audacity is not the word for that.
And merely wanting a comfortable living is not audacious, and no one who's not an idiot thinks it is, and is actuall othogonal to whether you have any integrity wrt open source licenses.
You can want, and have, that comfortable living either way.
