Hmmm. I see what you mean, but that was not my intention. The meaning the author -- me -- intended was:
"A drove people to B. It didn't drive me to it, but C drove me to D."
Expanding that:
1. Stop copying Chrome.
2. Australis copied Chrome and that drove a whole fork because so many people hated it.
[Full stop.]
3. Also, comparably, for the author, Quantum killed XUL and that is why the author switched away from Firefox.
However, I note that the marketing claim from Mozilla was that Quantum used the same type of extensions that Chrome used ("webextensions") and that this would be good for the Firefox add-on ecosystem. This is demonstrably false, as I laid out in the Waterfox article which this story links to, but it was what Mozilla claimed at the time.
