Just a general reminder, insulting proprietary software, is not a form of abuse.
Abuse is about a mixture of effect and intent, and it depends on the scenario and the types of harm that are caused to determine which of those are important.
Proprietary software, is itself harming people who are unable to pay for it, and in a deep way. I don’t think insulting proprietary software, which is by far the most dominant form of software, and the method of software creation that exploits and undermines free software efforts, can be meaningfully called a form of abuse. And I think people who are so attached to working on proprietary software that they get insulted by any insults towards it, should take a good long introspective period, and rethink their attachment to it and why they feel they need to protect that practice and facet of capitalism.
Thank you for reading.
