Agreed. However, interestingly, this is the legal type of insider trading, which is where the problem arises with defining it -- which is the other reason there's a reasonable debate about whether it should be illegal.
If you have insider information, it is illegal for you to make a trade based on that information. However, another way for you to use insider information is to not make a trade that you otherwise would have made, which is perfectly legal, because obviously it's impossible to criminalise a non-action. But both types of use of insider information can be equally profitable.
If you want to shore up a worthless company's share price, the last thing you want to do is to sell stock, as selling large amounts of it would signal to the market that it's worth less than believed. So, in such a situation, the legal non-active type of insider trading -- insider non-trading, if you like -- is the dishonest immoral thing, whilst the illegal type of insider trading is what would help thwart the immorality. That perverse incentive is why some quite serious experts want insider trading legalised.
