As noted, its not a 'big' difference, its the only difference
Which makes it a big difference. The two aren't mutually exclusive. 
But I get your point, Sean. Just trying to add a bit of levity.
I think whilst object desktop would go to auto renew, you are able to set it to do not renew again after renewing it if you wish.
Interesting, possibly changing my mind. So in other words, one can renew, then turn off auto renewal?
Yes, all Subscription services must have an opt-out system. Consumer Law demands no less.
The "auto renew" process is simply the easy way for most customers who actually do renew annually...
As Jafo correctly states, it is required by law.
What isn't required by any law or policy is:
Would the original Classic Desktop subscription still qualify as a Classic Desktop subscription after an opt-in to the auto-renewal, a cancellation of the auto-renewal, and then opting back into a renewal at a later time after the lapse?
To which Sean has answered:
There is no situation that can be posited where a Classic Subscription loses its designation or well-established attributes.
I tried setting this all out in a real world example earlier in the thread, which is better summarized by this post:
And it does not directly answer the question by @Narusegawa Naru or the follow-up example I posted, which can essentially be boiled down to the following:
Will a Classic Subscription always be considered a Classic Subscription, even if it lapses multiple times? And will the Renew option always been present, even if (again) there are multiple lapse periods during its lifetime of said Classic Subscription?
But a lot of it got lost in the minutae and my wording, so it's nice to see things a bit more simply stated as has been done in this thread and by Sean's post above.
Again, huge shoutout to @sdRohan, @Jafo, @basj0, and @BradSams for all their clarifications in this thread and others.
