Interestingly to me, the subscription model seems to further drive partisan reporting. The more the news organisations rely on subscriptions, the more they have to pander to their subscribers and main advertisers who tend to be skewed towards whatever political leaning that organisation had. It has almost forced them to be more extreme to keep up the clicks and keep the subs flowing in. Can't write a bad article about Apple or Google if they are a substantial part of your ad revenue and/or are restricting the distribution of your headlines.
They desperately need some other source of income.
