Amazon is a corporation, essentially a legal structure meant to encompass a group of investors. Investors range from its founder Jeff Bezos to small investors holding Amazon shares in pension funds and 401ks. You too can buy one share of Amazon for ~$2000 or invest in a low cost ETF that would own Amazon. The value of the stock is driven partly by expectation of future earnings. If Amazon were to lose future earnings relative to what investors believe they will receive, the stock price will likely go down.
On the extreme lets say that Amazon stock goes to $0, it would reduce the wealth of the world by about $1 trillion in stock valuation. That means that $1 trillion disappears from people's accounts (with ~$100 billion disappearing from Bezos' account). This would be wealth destruction no different from simultaneously reaching into every person's wallet and removing some amount of cash and burning it.
The whole "[corp] is not a person so [immoral act] is okay" is not productive.
