I've worked for a company owned by a single wealthy individual. When you're spending his money, and in Dai's case with no actual success yet (yes we can argue whether getting to the final is a success, but we didn't win the title), it is not a surprise that the source of funding wants approval of contract offers and cash outlay. Dai might feel he should be able to offer what he wants to who he wants, but it isn't his cash on the line.
I don't fall in to the category of fan that believes unlimited amounts of someone else's money should be spent to allow me to enjoy a fleeting moment of success. I've been to finals and enjoyed us lifting trophies, I want to go to more. That means our club has to be viable in the long term. We still aren't, yet. So some sensible oversight from DR seems perfectly acceptable to me and not a cause for concern.
