Time period B shows a clear net drop in market share in absolute percentage terms. You reframed it as a percentage drop from peak and combined it with time period A. That’s a shift in metric and scope, not a basis for calling the reference "completely wrong." It would only be wrong if that period didn’t happen which obviously isn’t the case.

If you insist on percentage points not ratios, then how do you apportion blame to me vs the CEOs before me? I was CEO for ten days. I stood up for it to avoid Mozilla going headless longer (Gary Kovacs stepped down by April 2013: https://blog.mozilla.org/en/mozilla/gearing-up-for-the-next-...).

If it’s all my fault, kindly say how. You will have to come up with reasons why Firefox continued to fall after I left and to date.
