Not blaming, but worrying about. There is plenty of software that can read Word's .doc files. Yet I store my data as plain text, as I imagine that the software will be killed or end-of-lifed in the future, even though I can use it fine right now. In the same way, I'd rather use a browser designed for an open, standardised Web.

Chrome doesn't have nearly enough market dominance for me to make accusations about it; I just want to minimise any future disaster scenarios.
