The FAQ has a list of reasons on why a post can be flagged[0][1], and I don't think it will affect your account unless you frequently post flagged content.
My guess would be the title, or the way the article was written.
IMO, the article makes valid points from both technical and privacy perspective, but it was written less like a critic and more like an attack.
People in Free software community will agree with the article as most knows about how bad a centralized proprietary program can be.
But the wordings could have been better so that it would trigger fewer people.
Got it, thank you. I think I'm not used to posting the full content in the title and I should improve it. Things like: "Is it popular to think Discord is a spyware in the OSS communities?". I'll learn and get better!
