As a rule, in any bona fide business, the change of ownership is smooth and without much trouble for the end user. Let's assume that freebitcoin does have a new owner. Still, then the question arises: why is he not interested in developing the platform? The fact that trivial problems on the site last for months and there is almost no communication with users indicates that the new owner is not particularly interested in the site's development.
It's not the incompetence of the new owner, it's something else.
Well, development costs money. To get a good developer team, you have to pay them a good salary. It seems either the new owner is not interested in developing the website, or he simply does not know whom to hire, or he still tries to rely on low-quality devs he knows. I believe the first one could be the reason. They do not want to spend money on development anymore.
Their website is running, and they want to make as much money as possible using the same product without spending much on development.
