What if a pool hides the blocks found?

I recently found this article but while searching for more informations I didn't found other comments regard it or if the system is really in danger or not.

Anyone could please enlight me?

Not sure what you mean by "hides".  A pool makes money by broadcasting valid solutions to a block.  By not doing so gives its competitors time to find a valid solution instead.

I don't think the pools can manipulate the block generation. Once the block is generated,the reward of bitcoin will go to the pool's address and be broadcasted to the whole network. I know one type of scam pool, who never release the reward to miners.
