I think you have to pick the low hanging fruit and go from there. For instance, we are here and already have made a small, but measurable dent to Reddit traffic. Imagine if everyone came over here, Reddit would no longer be viable as a profit company. Google would collapse if we all supported Peer Tube. Of course these are not going to change the world, but I am convinced if/when decentralization gets traction, we will find ways to implement it everywhere it makes sense. It is about balance as there are benefits to centralization and I am not suggesting everyone is decentralized, but right now the scales are out of balance and we have some tools to start to rebalance. We just have to want it. Well maybe need it which seems to be coming.
