EDIT: I suppose your comment is written in a way that it's not clear whether you're saying certain frequencies absolutely require meshes of a certain size to be blocked or if you're just adding that extra detail about the design of Faraday cages for the hell of it. But...
Original comment: It doesn't have to have holes to block radiation. A continuous sheet blocks all frequencies. A mesh is just nice so we can see through the cage or allow air to pass etc.
From the page you linked: "A Faraday shield may be formed by a continuous covering of conductive material." "... if the conductor is thick enough and any holes are significantly smaller than the wavelength of the radiation."
Israel has malware for phones that is unnoticeable on devices. They could easily make phones send in text message votes without the phone owners noticing. It's a propaganda event they can't afford to miss.
Steam packages its own Linux runtimes and seldom uses system dependencies. Maybe SteamOS has a different runtime for Steam Deck though.
