When you say decentrlised you're saying that the hash power by an entity is so large that only they can pick and choose the transactions from the lowest to highest fees? and hence they have the power to to choose who's transactions get processed? well that's what competition is for, all we can do is "act with our feet" so to speak and just choose another cryto for transactions, no harm done there. Another cryto will step up to accomodate, there is no doubt about that. Bitcoin will just be a valuable commodity. I understand that wasnt the intended purpose, but thats life, things change, and I say that it's not possibly a bad thing. but happy to read other oppinions
