You do get to upgrade for free on the products you own for the dot releases... that has always been WebAssist's policy -
I am not sure of your logic in this argument... you still got the value of what you purchased AND furthermore... you would still be getting value if you decided to now get the subscription.
How you ask? Well, look at how many new products Web Assist rolls out each year... if you are like me and you end up buying all of them, then the subscription will actually ensure you get the latest and newest tools while guaranteeing that your costs for extensions won't go up.
I have had SuperSuite for almost two years - so I am THRILLED that they went to the subscription model. Think about it, they release at least 6 new products each year that even with discounted pricing because I am SuperSuite owner cost me about $300 plus per year - and as a pro designer, I really can use everything they come out with. Well, now, I am guaranteed to always have the latest and know that my yearly costs will never go above $200.
There's more positive to this than a lot of people are seeing.
