I believe that you started out that way. The problem with that first comment was that you began with an insult ("I immediately know that their technical understanding of the current backend and ops technologies is years behind"), which provokes people rather than informing them. Also, your comment included name-calling, which the site guidelines ask you not to do. Could you please review https://news.ycombinator.com/newsguidelines.html and follow the rules when posting here?

After that, you followed up with personal attacks and incivility. That's definitely flamewar. You weren't the only one doing it, but that doesn't make it ok.
