There are liability issues for any sort of "money" or finance paper that don't exist for regular news reporting.

Under regular news reporting journalists have no legal obligation to their readers or the truth. They can say anything they want, essentially. It can be accurate, or not. It can be the truth, or not. It really doesn't matter. You can be lying for personal profit or political effect or any reason you want and it really isn't something you can get sued over. Just have to avoid tripping over defamation laws.

Where as if you are dealing with financial reporting there is legal liability. It is possible to get busted for committing fraud, it is possible to get sued for misleading information.

So keeping these sides of the business completely separated is probably a good way to limit liability.
