It’s not so much “worried” about the sunk cost, it’s simple practicality - you already have a PS5, might as well use it. Just don’t give Sony money for PS Plus or buy any of their future consoles. If most people cancelled their PS Plus accounts, I guarantee Sony would notice far more than a week-long blackout. But they won’t.
A protest by gamers who are worried about the sunk cost is less effective than one where Sony is worried about their sunk cost.
