We should refute old and false narratives about Ruby or Rails
I happen to agree a lot with Amanda Brooke Perino here

That’s why I almost always comment on Hacker News or any forum
where I see people still spreading old narratives about Ruby and Rails.
I think we should not just accept them and move on but reply to them and
show why the narrative is wrong. Maybe not with the purpose of
convincing the author who is spreading that narrative but for other
people who might read that without knowing Ruby and Rails. If no one
refutes these statements, people from outside our community could take
them as truth.
I believe it’s important to engage with empathy and try to have a
dialogue with those spreading this myth. We should try to understand
where they heard about it, when they last checked the status of Ruby on
Rails, and how much they know about our ecosystem.
