Given that at at least one of your competitors provides an app that I consider to be superior to 'Skybox', especially in the area of playable media formats, it's my opinion that you may-well shoot yourselves in your corporate foot by going-over to a 'subscription' model. 'Skybox' is nowhere near mature enough a product to justify the subscription model.
Personally, I despise the 'subscription' model because I've yet to see how it benefits the customer anywhere near as much as the provider. I have found that software development suffers due to a less-urgent attitude toward fixing bugs and/or introducing improvements. 'Subscription' models seem to encourage developer-belief that the customer needs the developer more than the latter needs the former (i.e. Adobe, Avid et al).
I have abandoned, and will continue to abandon, all software that requires a 'subscription'. I refuse to 'rent' software.
On the other hand, I do not expect to have an unconditional 'lifetime licence' to 'Skybox. I have no issue with periodically paying an upgrade fee for a new 'version' of 'Skybox' provided that the new version actually has something 'new' to offer. In other words, don't try to pass-off bug-fixes and cosmetic changes as 'improvements' or 'new features'.
At its most basic, moving to a subscription model is an example of the dubious practice of 'moving the goalposts' whenever you feel like shearing the consumer-sheep a little bit closer to the skin in order to get an extra penny out of every hide in the flock.
