“Your” money isn’t being used to work against you, you are voluntarily paying for what is currently on offer. They’ve announced major changes in advance so you have plenty of time to decide to cancel after the current month if the future service is not to your liking.
It’s rather entitled to think that your monthly payment gives you some kind of veto authority over their product plan. If you don’t like how they run their business, that doesn’t magically create the right to use their work on your terms.
The whole point of a subscription is to support an ongoing service _to you_, if your money is used to enshitify the service and make it work _against you_, there no point of paying it altogether, you will be better serve by piracy (as you don't provide them with money to enshitify it, nor to lobby against your interests).
