For the hobbyist who has never made a dime off of the software, annual maintenance costs do add up but the beauty of maintenance over subscription is that you are actually "owning" something at the end. With subscriptions, what I was once paying for maintenance now just gets me a right-to-use for a limited time (1 year). As you don't own it, once you stop paying it goes away.
I would imagine that most digital enthusiasts like myself probably have X-Particles or some other 3rd party renderer or any other plugin that has maintenance programs (DEM earth, etc).
So when C4D was pre-subscription, you were paying $720 for C4D, around $300 for the Insydium maintenance programs, probably another $300 for your favorite 3rd Party Renderer, and you could easily set aside another $100 to $200 to support any new releases or updates from your favorite plugin developers. Plus, you probably are going to want to keep your hardware up-to-date and plunk down close to $3000 every 5 to 6 years for a new computer/monitor, etc. Therefore, for a hobbyist your annual costs to keep your software and hardware current come to easily ($720+300+300+200+$600) to over $2000.
Do that for 10 years and it is like owning another car (we do keep our cars for 10 years).
But with software under maintenance, every year it gets up-dated. Under a maintenance program, should you want to stop paying for maintenance, you leave the program with the latest and greatest of everything because everything still works. If you did 10 years on subscriptions and decided to leave, you have to go back and hope your last perpetual license from 10 years ago still works on your current OS or GPU. For any new plugins purchased over that 10 year period, there is no guarantee that they will work with your last perpetual license. In short, you are still paying the same amount as with maintenance plans, but should you leave a subscription program after an extended period of time you may not even have an old car to go back to...you could have nothing.
So going on subscriptions in year 1 does not bother me....but I think long term. What if 10 years from now and thousands of dollars later I decide I can no longer afford this hobby. I then have nothing. That is what really scares me and that is what makes me think about leaving it all now and going to Blender. Yeah I lose all that time with training, etc. but why invest long term in something I feel financially locked in to.
"Stop paying and it all goes away" - that's not a good feeling to have with something that is supposed to give you enjoyment. This is a hobby to me after all.
I do love C4D. It is an awesome program in more ways than one and it is on a good trajectory. But so isn't Blender and Blender does not make me feel trapped. If there is any plan in the works that says "stay on subscriptions long enough and you won't leave empty handed", I would be all in as that is a win-win situation.
But I don't think MAXON is thinking as long term as I am.
