There isn't an issue. The issue is software patents.
What's hurting people is self-proclaimed experts writing authoritative blog posts about what technologies people should chose and presenting it as if it were legal advice.
This entire drama is a 100% repeat of what pops up on almost a monthly basis because some random developer finds out about Facebook's open source patent grant and decides he has an opinion without even understanding the basic underlying concepts.
There are legitimate issues worth discussing, especially around the notion of open source purism (i.e. whether React should migrate to the Apache license to make it more compatible). But instead of having these discussions we get ridiculous unfounded opinion pieces by yet another "dude with an opinion" who didn't even bother validating his basic premises.
First off, the commenter doesn't have the ability to silence anybody (presumably).
Regardless, spreading misinformation or at least doubtful information is only going to hurt a cause. Blindly lashing out at things you don't truly understand is foolish. Encouraging others to do so is dangerous.
There are several issues with the article itself, but I think one of the most damning actually comes from the updates/notes at the top. Namely, that the author is "neutral and unbiased". Nobody is completely without bias. Especially if you feel so strongly as to write an article.
"Beyond immoral" seems to me somewhere between excessive and totally wrongheaded.
Bad advice has consequences and bad legal advice often doubly so. The law is nuanced, convoluted and often unintuitive. People really are better off going to an expert!
Please reflect on how you are hurting everyone, not helping.
