It's because iconera tweets threads which gain traction in some of the worst places on twitter. The fanboys see the threads and decide to create accounts.
It's a good strategy to promote growth, but there is a sickness happening in gaming right now due politics and the fragile state of the "console wars" where it is clear that Sony is about to have a near Steam like monopoly in the "hardcore" console space.
The PS5 Pro is simply an extension of that, as is Astro Bot.
The PS5 Pro represents not only every 3rd party game playing the best on PlayStation, but even Microsoft games.., everyone knows Microsoft is going fully 3rd party, but that bubble of denial will burst when Halo is announced on PS5.
Astro Bot is a referendum on the idea that PS5 doesn't have any games. Unlike Helldivers 2, it's a PS5 exclusive and it's fairly likely to win GOTY. If it doesn't it'll probably be beat out by FF7 Rebirth... yet another PS5 exclusive. Other contenders include Wukong, which for now is a console exclusive and potentially Metaphor, but I don't see that happening.
