Chromium is imposing the extra load on the system, so yes it is the abuser in that sense. That they are doing it for what is a good reason for the app's users is immaterial to whether the effect is bad for the root DNS servers.

If Karen takes my sandwich from the company fridge, so I take some of Jon's lunch, so I don't starve, I'm not innocent because Karen started it, I've created a situation where there are two arseholes instead of one. This isn't quite what is happening here as the root servers are effectively a public resource and stuff in the fridge is all private resources, but close enough to make the point.

They should have all the blame for deliberately breaking part of agreed protocols for their own gain.

But that doesn't make anything we do in response to that right by virtue of us doing it because we have been wronged.
