If I'm correct essential fixes will be implemented until C2 official retirement.
That said as the nature of software development and services progresses, I take it that C2 will soon date.
But that's applicable to everything in this fast moving world:D
As a user of a one of their products, it's up to me if I want to continue my involvement with them.
Of course in this case they've replaced something with the next thing. Which is still the original product. (Long story.)
If they retire a product and give enough notice, they are not obligated to refund any money for dated software if I'm correct.
I'm sure that as a business they've also used services that one day told them: "Canceling so-and-so tomorrow.", which then forced them to change business practices whether they wanted or not. Or get in the unemployment-line.
As much as they are a service to us. That service itself will remain their first priority. This is not to be rude or anything, it just is.
