you are correct, technically he should have said 'decentralization' but 'freedom' has more brand recognition. and most people will not look up what they don't know and understand (anything unfamiliar). Instead they will ignore it, and focus on what they do know and understand. this is the importance of marketing. so unfortunately this post would probably not have gotten much engagement if he was semantically accurate. but because he twisted the truth, its reached further. so the philisophical question is, be semantically honest and reach no one? vs bend the truth, and reach everyone?
