I can see this happening exactly as you spell it out.
The centralized institutions that are in control now are not going to give up the power without a fight. Of course, we saw this happen in the record industry, to no avail. However, they did create a mess for a while before having to toss in the towel (remember suing their own customers?).
There is no stopping decentralization in my opinion but they can make it hard for a while. The one thing they have control over is the message. This is why I think we need to promote the idea of decentralization over cryptocurrency or blockchain.
Highlight things such as censorship, security, and centralized power in the big tech companies.
These are all things people are really starting to grasp onto.
