I'm not saying every game and software on Steam is quality or proven to not have malware or spyware packaged in the games.
I'm saying Epic Games Store and Launcher itself is spyware, that actively snoops through user's personal files well beyond the scope of its install directory and phones home encrypted packets of the results. And Epic Games will not give proper response to why it's doing this or what it's returning.
Valve at least has been forthcoming about what Steam looks for and why it monitors specific ports, as part of VAC.
