No, I scanned the article and made a judgment. If you don't want to be judged on your use of English, improve it. What works for computer languages should work for English too.
However unfair you believe it to be, people are going to judge you based on your use and misuse of English, and they will often do it in a flash. Complaining about it won't work -- all you can do is adapt and overcome, which I am sure is within your power.

I believe you "led" the redesign of a major Website.

Under the circumstances, that's a wise choice.

I believe you mean "where they're coming from", as in "what their attitudes are", rather than their place of origin or residence. But I could be mistaken -- the above might be an Americanism with no British corollary.
I find it very funny that people will unsentimentally dissect a piece of computer code (computer "language") with the aim of extracting a 10% improvement in its running speed, or readability, or maintainability, but will bristle at the suggestion that the same high standards could be applied to written language.
