I am here to tell you that companies are actually getting more from you when you subscribe to their services. Why? First of all, for some reasons we humans tend to subscribe to something and then forget about it immediately. How many subscriptions have you forgotten to cancel?
It's their business, everyone starts a business to get good profits, I get more from my clients when they give me contract and I give them a good return for their money. We've needs and since you cannot do everything, you'll have to subscribe to some third party services to help enhance your work and keep your work profitable.
Second, when you are subscribed to something in a certain amount of time you might not really use it as much as you thought you would. You might be too comfortable that the service is just there and easily accessible therefore not really making the most out of it. Like in a gym membership where you pay for the whole month but you only go for a few times.
Yes, sure. I pay for cable subscriptions and use it few times but the most important thing is that this services are available when I need them and that's what matters the most.
