Ok so if something previously was free and now costs 1c per transaction, you would think "Stripe increasing price infinitely" would be a good title? Just because it is true that doesn't make it a good title. A good title should create a realistic expectation of the article content.

No that would not be good. I agree that you should choose the correct way to represent something.

But here a 50% increase creates a realistic expectation to me.

Congratulations, you’ve identified a misleading statement that has nothing to do with the present situation.
