I have spent my entire adult life attempting to avoid subscriptions and only use services I pro-actively pay for, which has become rather impossible over the last decade.
Returning to that would be great! Of course, a large amount of SaaS companies would be very unhappy with this - recurring billing on customers who forget about the service is a major revenue source. There's an entire industry built around "not-quite-scamming" people in this way.
Lately I've taken to using whatever credit card I have that is going to expire the soonest, or a virtual card, and then not updating it on customer portals. In many cases, this allows me to use a different card to make a "one time payment" after the recurring payment fails, which prompts me to evaluate whether or not the service is still something I need every month.
That'd be wonderful for consumers and terrible for shitty companies. But it should be that way.
