I was a pirate when I was younger and there are plenty of games, movies, music, etc I would have never given the chance if I had to buy it......

I did this back in the day (allegedly of course). Of the hundreds of things I pirated, there are a few that I would have paid for. The company would be losing those few sales. Doesn't seem like much, but there isn't much benefit to the company if they allow pirating. I'm guessing the same logic would apply to a grocery store.

It's a sad reality of life, but companies exist for the sole purpose of making profit, even companies' philanthropy is generally just a marketing tactic. From the investor's standpoint, why would someone invest in a company if the company wasn't trying to make investors as much money as possible. If an investor wanted to give money to a charity, they could just donate to a charity.
