The rotating services around the year is the most logical especially given no discounts for "continuity of service" and that I'm usually only binging one show per month.
In some cases it is actually sort of the other way around with effectively discounts for "discontinuity of service" because some services offer discounts to people who have cancelled to try to get them back.
For example I've had offers from Disney+ for a month of Premium for $3 and for Basic at half price for up to 6 months. (To be clear the latter was still billed monthly and could be cancelled at any time. You didn't have to keep it for 6 months. It was just that after 6 months the monthly rate would revert to the regular price).
