I can't believe I have to say this, but I've seen people being extremely toxic about people complaining about the direction of NGS. While it is possible to go too far (such as threats, actually just whining, or anything else that makes your argument into just some kind of flame), most of the time I've seen people attacking people, it's when they didn't do anything wrong, they just stated what was clearly going on in front of us and said they want more content.
Even the people that complain about lack of content on the Twitter, I'm pretty sure most of them know the person on the PSO2 Twitter account has no direct control over the decisions about the game (as in maybe they report some stuff we say back to higher-ups, but what they report doesn't have to be used, but who can really say). But if you want to get a company to do something you have to make what the company is doing wrong very publicly visible.
Whether SEGA will do something or not, we can't really say for sure, but if people are to stay silent about every issue they have with the game, the chances they will change the direction of the game are 0. The point of freedom of speech is to be able to call out the people in charge of well... anything, with proof of their wrongdoings and hope a change will be made because of it.
There's a difference between wanting something because of entitlement, and wanting something because it's something that is expected of any game of this genre, or even just based on what was in base PSO2.
If you try to silence people that are simply expressing their opinion (and the way they convey their opinion doesn't have misplaced malice) by saying they're just whining, then you are the one that is problematic.
