An economist would say that making another company less valuable is good in most cases because it usually means you are outcompeting them because y(u found another way to supply that need more efficiently.

the real reason this is not good is because it doesnt and cant easily capture what value flows to the customers and if the market is competitive all the value will eventually flow to the customer since pricing aboce marginal cost will get competed away and moat innovation is essentially making marginal cost lower
