You are asking me something to which you already have an answer - I assume that the people who have been working on this project for some time are not the same ones who have been working on it for the past ten years - it is logical that the old team would fix everything within a reasonable time.
Why would someone sell a profitable business (if it still is) after 10 years? Well, for the same reason why many successful companies are sold and change owners, or simply because the owner has made a lot of money and wants to enjoy retirement.
While you might be right, this is just speculation. Communication has never been their strong point although it was a lot better when TheQuin was still working for them as he was pretty responsive on this forum when there were issues/complaints. The site might have changed ownership and maybe in the background they are working on fixing the issues, but we can only guess at this point.
