They aren't being rude, just increasing the sample size and reporting back. Perhaps we're witnessing SEO for different regions, regulations, and aggregate history of the two.
I'm a native English speaker. You're feeling that there is a belittling connotation is valid.
The first quote is potentially a dismissal, which is belittling. However, if it stood alone, it could also be interpreted as the person backing off because they lack qualification to interpret the results. But the second quote includes dismissal terms like "complaining" and "not objectively" in a demeaning context.
So, with all that, I'd say your impression is valid. The context highly suggests that these responses were meant to belittle the parent author's contribution to the conversation.
Here is my take on the parent's search results. The God Of War director ( Cory Barlog ) was a big part of the marketing for the game. And he did some in-game commentary for it too. So, this suggests some kind of SEO manipulation. But it could also just be the google spellcheck guessing wrong.
Intentionally? I'll assume good faith. Under that presumption, my best interpretation of that poster is "socially unaware, likely prone to nitpicky argumentation."
The poster who said he was having difficulty getting good results from Google, was obviously venting about his own personal experience.
Next comes along another poster who says "I tried it. I don't have your problem." Another post down, "... The problem you're complaining about doesn't actually appear to exist, at least not objectively."
Excuse my outburst, but who the fuck says that?
The original poster was venting about a problem he experienced. What good can someone do when he comes in and says that he doesn't experience the same problem, and states that it likely doesn't exist? There is no upside here. There's an only a downside: being rude.
I'm not trying to be rude, but I honestly believe a lot of the complaints people make about how useless Google's search results seem overblown. I use Google all the time, sometimes for obscure results, often for technical stuff, and the worst I've ever had to do is look past the first page, but often the first page suffices.
Google showing results for director's commentary of God of War when someone searches "Lord of War director's commentary" is arguably not a failure on Google's part if more people do search for the game than the movie, regardless of the incorrect title.
That said, I completely agree with the theses of TFA. SEO is a cancer.
Also as a non native speaker you appear to be rude.
