> your whole subscription since the beginning will feel like a waste.

This is such a bizarre way of looking at something. I've canceled many subscriptions because of changes made by the company and I never felt like the time I already paid for was a waste. I got the thing I was paying for, then it changed in a way I felt like it was no longer worth paying for so I stopped. It doesn't change the time I was using it at all.

If a company taking your money and using it to make the service works is your line in the sand I've got bad news for you about how almost every single companies uses the money you pay them.

And there have been a ton of things I just lost interest in over time and wasn't getting value from any longer, so I (usually, eventually) canceled. Doesn't typically mean my earlier subscription was a waste. When I got rid of my cable TV, doesn't mean I wished I never had it.

If your favorite restaurant changes their menu, does that make your past meals feel like a waste? It seems like a textbook economic transaction to buy when the deal is good and stop when it isn’t.

Restaurant aren't subscription based, you pay for a one-time meal.

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).

“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.
