As a user of Hackernews you're not thereby entitled to anything at all.
As a member of the thing(forums, discord channels, facebook groups, any online community and real life community) you're not necessarily thereby entitled to anything at all.
Even as a user of some proprietary software, you're still not entitled to anything except perhaps critical bugfixes and security updates. Software is sold on shrinkwrap basis. You got what you bought.
It doesn't mean expressing your opinions about Hackernews, the thing or some proprietary software, even negative ones, is inherently wrong.
