In aggregate yes but individually no. Unless there's some wider structure organising individuals to withhold their consumption for explicit reasons that the corpo can hear then your unsub won't have any effect beyond your own sense of self-satisfaction.
That's not to say that it's pointless but if you want to hurt a corpo you need to organise.
Yes and no. Yes, we’ve been stripped of our ability to protest in any real and meaningful way outside of “voting with our wallet”, but no because even then it’s a futile effort because these sinister people/corporations are so prevalent in our culture that we cannot escape funding them; either directly or indirectly.
Take Nestle, known evil corp that thinks water is a commodity and not a basic life right. Or General Mills, who recently drew the ire of everybody over their proposal to take away worker benefits. And I’m sure there are more that I’m not thinking of; that if you put them all together, would make people very hard pressed to buy the things they love.
Bitching online while still pre-ordering that shit is not activism lol
Your comment is a perfect example of what OP is talking about. You believe that if gamers changed their purchasing decisions on mass, then companies would have to change. What is that if not activism? You're treating capitalism as though it were a democracy.
And you're wrong btw, Game companies make games for investors, not gamers. If you don't believe me then please explain why so many live service games get made even though gamers have clearly voted against them with their wallets.
