The point is that blockchains have different incentives for different parties, and the interests of the most influential people don't necessarily align with those of the users. So the vast majority (users) are just really switching to a different master.
Eg, I had a passing interest in BTC, but I my interest was in the very old school "buy pizza with it" kind of use. That usage is of no interest or importance to the current BTC system, and it doesn't matter one bit how many of me there are.
The people who matter are the people who commit to the repo, the people who run miners, and the people who run exchanges. The desires of the 99.9% who aren't any of these are nearly irrelevant.
Re: trust the devs: do you trust the electricity in your house? What about the wires in the wall? Do you trust others to follow traffic rules?
