I read it as being personal at first but on second read interpreted the “antithetical” comment to reference the issue that they were breaking the license and limiting the users freedom.
I meant that my comment was a personal feeling about the license, and not about any particular users or violators of the license.
The post says "we would prefer if people so antithetical to our values did not use and benefit from our labour", and that is clearly not a criticism of just the nature of the license violation, but the people who are violating it.
Can’t a generous person who chooses to give away something (on the condition that anyone who chooses to accept this gift does the same) criticise the character of those who take advantage of this kindness for their own personal financial gain?
