They could be doing that or maybe not, but the good thing is that they created BTC in such a way that it does not matter what they do, the network runs perfectly without the creator or any central authority; that is the beauty of BTC. Satoshi is a genius to create something like BTC, and if he wanted to be around and make himself known for all the praises, he would have done that, but he instead completely protected his privacy and never exposed it, and so it is better if we respect that.
