The short answer is that it won't effect you at all unless you decide you want to be part of the program. If you do join and you have previously purchased, then if you cancel the subscription you can continue using the software you purchased. People who have not purchased and cancel the subscription will no longer be able to use the tools, but all web sites created will continue to function normally.
There is really nothing for existing custmers to be afraid of, we are just trying to lower the barrier to entry for new customers and offer a subscription model for those who want to be ensured the latest version of everything at a fixed annual cost.

Let me start by saying I have come to really like WA extensions. But this new subscription service feels like a slap in the face.
I think the thing that upsets me the most is covered here, above. (Sorry Ray). Lowering the entry barrier for new customers is not going to play well to those currently invested in your product.
Since 2008 I have purchased almost $900 of your extensions. At first I purchased the Super Suite and a couple of upgrades and solutions since. This was a difficult and serious purchase for me.
So now, the new kid on the block can hit the road running for $99.98. That works out to be 4 years of the latest extensions for the same amount as what I spent this past year+.
I have to be straight forward and just say it. Giving current Super Suite owners an upgrade price for this is laughable. And I shouldn't have to call sales and beg for a freebie. I should have received an email with a thank you as a current customer and an offer to subscribe, with no activation fee. What exactly is the activation fee for? It makes sense to have an activation fee or entry fee for a new customer so that you don't start a $20 subscription service only to have them cancel 4 weeks later. But what is this fee being applied to for current owners of the extensions?
In the end, this does affect us. I had to invest hundreds of dollars to get my first development job and there wasn't any profit from it. Now someone can invest $79.99 + $19.99, create an entire shopping cart or CMS and then unsubscribe. They make a profit for very little investment AND still have the code to reuse.
That's how I feel, sorry if it steps on toes.
