This is akin to the "boycotts" people have done against gas stations for high fuel costs. It doesn't work. It's always like "on a Tuesday, don't buy gas"... but you weren't going to until Friday anyway. And then you buy it on Friday, the books balance exactly the same, and there is zero actual impact.

You want to impact Sony? Stop buying games on PS5. Not for a week. For this entire console generation.
