Investors are very happy with profit over security choices. Moreover, decisions to maximize profitability thinking only in short term is also not bad for them if they perceive that can sell their shares before the consequences. A company that do not place profit above other things is not a good company to invest money and see it grow. A company will invest in security only as long as it increases profitability. Doing otherwise is not maximizing profits and lose investors. If you are a "security company", surely this means that you need the security to sell the product and get profitability. Other companies will have other tradeoffs to choose how much they invest in security to maximize profitability.
(Going by Matt Levine's "everything is securities fraud" logic here to see if that might actually change behavior…)
