I don't want you to look in the other direction even though I asked for clarification regarding the flaming posts against EA.
What I want is to say is that I accuse VGChartz moderation team of being biased pro Nintendo. Which is an accusation that I'd do today, one year ago or one year in the future. It's a general accusation, not a justification.
The site is biased towards Nintendo in the past the present and without a doubt in your eyes the site will be biased towards nintendo a year from now? Do you ever get the feeling that since you've already made up your mind the future actions of this place as being pro Nintendo then there's not a whole pile they would be able to do to change your mind, you are the one with the bias against the company/their fans and people who point that out to you are being "pro Nintendo" I would say right now that shit posting about Nintendo the company who are sat on top of the sales charts each week is going to draw some flak from people because sales indicate that the majority of gamers are very happily enjoying the Switch right now, based solely on weekly sales by attacking Nintendo as a brand or their fans you automatically put yourself on the side of the argument which has less support, straight up numbers on the front page tell you this in black and white, there's no bias in that.
Also in regards the post you linked where someone was ragging on EA because EA as a company is doing what it can to get all the cash they can from their gambling mechanics before laws prevent them from doing that, calling EA scummy for their current lies towards politicians and those asking them for information is attacking.... EA, as a company, the target of the flaming is EA a company who doesn't come to this site, there are fans of EA games on here but they're not the attack of this sort of post.
Your post of "Nintendo fans X and Nintendo fans say Y" who is the target of that? is it Nintendo the company? No it's not, it's the fanbase, it's the users of this site, you are making posts which implicate what each one of the 200k purchasers of the Switch each week think, that they all have a single mind and goal when it comes to what they play and how they all just like a certain game type.
You really have to consider when you are posting who is the target of the criticism in your post, if you suggest that a company has bad practices and can give examples then that's a fair thing to say, if you say that all of a fanbase of a company think a certain way or act a certain way then you cannot prove that as a single person of the millions of Switch owners who doesn't fall in line with the narrative you're driving means your statement is false and both a generalization/attack on that group.
Rather than asking the question of "is it okay for me to be a dick to this company instead?" why not just avoid making antagonistic posts towards any group? Or at least don't start with statements about how all the fans of a company you don't like all do 1 thing?
