They've done the calculation. They'll lose X income because of subscribers who leave, and they'll get Y extra income from the ones who remain. If X < Y then implement policy.
I’ve worked in a finance department — and this is a very idealistic view of how such decisions get made.
Companies increasingly no longer even care about income.
They care about what boosts investor confidence.
So even if implementing a policy lowers operative income, if the growth in stock value offsets this, aka. number-go-up == true, the policy is implemented.
