The response is fine.

Entitlement and, really, some of this crosses the line into bullying of the foundation and the maintainers, should be dealt with robustly. It will help to reset expectations around what's reasonable for the relationship of those developing LibreOffice with the community of users.

People need to recognise that they get a huge amount of value out of LibreOffice, for which they aren't required to pay a penny, so it's not unreasonable to be asked if they would like to contribute something back in return.

But amongst large populations of people, when it comees to free things, some portion of that population will always undervalue that free thing and fail to recognise how much benefit they get from it and start acting entitled. There's nothing wrong with calling that out.

It doesn't look professional when you loose your temper, this article is comparable to that.

When reading it, I kept thinking that the writer was too emotionally involved.

I agree, what's the alternative, not only are they not allowed to ask for Donations, but now they are not allowed to complain about entitlement?

How ridiculous would that be, users that get stuff for free setting the rules on how they should receive the free stuff.
