True for some altcoins, but not Bitcoin. You can see the hash rates here: https://blockchain.info/pools
And even then, most pools are largely decentralized and heterogeneous -- controversial political/technical changes by the pool owner would absolutely trigger an exodus of hashrate from the pool. (As happened during the BTC/BCH fork.)
But small enough to have miner pools controlling 50% of the hash rate.
