Well GOG already exists, and functionally so does piracy. I have zero worry about my games because even IF steam heel turns when GabeN dies, I'll just redownload my whole library and start pirating if not fully switching to GOG. Functionally the PC gaming sphere is not at risk in any way because of Valves position as PC gamers by nature are more web aware than other demographics. In fact, with the Steam Deck, Valve may actually be bringing more of the casual gaming sphere into the PC gaming market
