Libraries are good, and a great community resource that should be treasured. However, no library can have the sheer volume of information available that YouTube and the Internet do. There is also the benefit of having more kinds of content, plus the ease of putting information out there.
For example, say I want to learn about the specifics of the defense economics of the war in Ukraine. Sure, I could wait 15 years for books to be published about it, hope my local library buys it, and then go and read it. Or I could log on to YouTube right now and go watch the latest Perun video on it which is also more entertaining. This also is an example of speed of new information being available on current events.
Both of these things have their strengths and weaknesses but it is simply a fact that YouTube has changed the availability of information to quite a high degree.
Tbf there are a lot of people who love solving cryptic puzzles and getting info out of very little, thats why ARGs are a thing. The good thing is, you don’t have to engage, you can just wait for proper announcements but for the people who love this shit they get to have fun, and presumably the devs too for making it.
And imo it shows that team cherry is interacting with the community in a positive way and might actually be finishing the game
