See this is what I mean "boycott these 763 companies and their subsidiaries" is unactionable, you might literally starve trying to do this in earnest and most people will take one look and go "well we have already lost and this is pointless".... contrast this with "Make them dump the Bug Light down the drain." That is targeted, that is simple, conveyable, actionable, achievable.
People have boycotted gas stations by simply not buying gas on Tuesday and Thursday, they are still buying the gas but they are fucking with the business economics, making their staff redundant on Tuesday and insufficient on Wednesday. We need to do the same. We will never stop people from buying games and when we really start digging we will find SBIs everywhere. We are going to have a hard time finding a AAA game that hasn't been poisoned with this shit. We can't change it all at once but we can fuck with the studios and cost them money.
