The OP implied unaddressed bad policies/practices within the companies whose games we've bought. Of course if a company rights the ship and holds bad actors to account, they can get a second chance, but once you know your favorite diamonds are blood diamonds and are still being sourced under cruel conditions, you can't then say in good faith that you just like that source's diamonds, and since you're not personally putting the gun to the heads of slave laborers, that makes you just an innocent consumer playing your tiny role in the world of commerce.Which is fine until you literally can't buy anything that is made under completely ethical practices. Like smart phones and diamonds for example.
The OP did state that they already own the game so there is no harm playing something long after the fact, you are right on that point.
But in regards to future purchases, here is where my confliction comes in:
Let's use Blizzard as an example because they are obvious right now. Those allegations are fucked up certainly and the people within responsible should be fired (and it looks like they are cleaning house). Do you then further hate the company and all the people there (victims included) after the bad guys are gone? The company is just a name, it exists no matter who works within, so if something bad happens at the company do you forever shut yourself out of that company's products even if you really enjoy them?
And if Blizzard cleaned house and made good shit again, would it then be okay to support them or does the name have to remain forever tainted?
Not a fan of Blizzard and honestly don't know what this most recent kerfuffle is all about, but if people are just learning of their wrong doings and nothing's being done about it, then anyone who logs on to their servers is complicit in their practices. Does that make them bad people? No, but they are certainly complicit supporting bad behaviors.
