There's a quite interesting psychological effect in play in that situation, which is exploited by these long trials.

People generally don't want to give up something they have access to, even if they don't really need it. They give you enough time to get used to having it, so that your brain is telling you it's an integral part of your life now.

I remember when I got trial Amazon Prime, to watch the first series of The Grand Tour. Years of renewals before I finally dumped it as a statement against "The Boys" for showing a guy getting graphically raped and murdered by a woman.
