I bought the plugin User Online author Kairat Bakitow on 12/24/2013 price $10 now disappeared, only puts "Plugin was deleted by owner".

Today has been a new one for sale User Online author Sergey Pryadkin price $15.

And apparently it's the same.

What happened?

I can buy new for $ 5?

It will happen the same thing with other plugins?

Sell the same plugin but more expensive?

Let those who have bought unable to download?

If Kairat Bakitow has abandoned development of its plugins as you may have just gone this?

I think that if an author abandons the development of Oxwall or plugins, their work should be freeware for the benefit of the community, and perhaps another developer to continue the work.

What do you think? What Oxwall, Kairat Bakitow and Sergey Pryadkin think?
