The thing about this shit is...
Microsoft, like Google, is now a user-data driven company and they have already made loss/profit ratio analysis on this long before they released the price increase. They're absolutely banking on people cancelling but making up the difference and then some from the people who stay.
For a thought experiment let's consider how many subscribers they were reported to have in Feburary: 34 million. Let's assume that everyone is paying for the highest tier to make the math easier. So current income would be 34 million user x $20 a month and thats $680 million a month. New income of 34 million users x $30 a month is $1.02 billion. The difference is $340 million a month. Let's divide that by $30 a month. That gets us about 11,333,333 users. So they can hemorrhage over 11 million users and still break even. To make sure, let's subtract 11 million users. That gives us 23 million users. 23 million users x $30 a month is $690 million a month, a cool $10 million a month above current profits.
For final context, 11 million users is roughly 32% of their entire subscriber count. They can afford to lose a third of the people subscribing and still make money.
The math doesn't bode well for us who vote with our wallets.
