That does literally nothing though. Buying a share of a company is like buying a used product, none of that money goes to the company. The only benefit to a company is the share price rising, and your contribution to that is effectively zero, and it only matters if the company issues or buys back shares, which is somewhat rare.

It’s the same reason that buying “green” shares does nothing.

Invest based on what’s most likely to give you a good return, even if you don’t agree with their products. And then buy products based on your convictions. If you want to feel like you’re “sticking it to the man,” use the profits to buy from their competitors.
