Sadly i don't think its bots. I have seen these kinds of people in other fandoms as well. Its most common when its the fandom of a large franchise and a particular entry of that franchise is significantly more popular than the other entries. That more popular entry will get tons of endless unwarranted hate from people whoe prefer the other ones. Its extremely unhealthy.
IIRC, there is only like a dozen games or so that came out on PS5 without coming out on PS4 as well. Almost everything comes out on both even now. We are at the point where the graphical improvement from one gen to the next is negligible. The companies doing this have the hard data and they know PS5 sales are lagging behind.
That's the biggest sign of the failure of PS5 as it shows a massive hesitation to adopt the new hardware from it's own fanbase. My PS4 keeps sending me ad deals to get cash back for a trade-in of my PS4 and upgrade to PS5. They are getting pretty desperate.
