I think this site is from the UK where companies are plural (they are made of people after all). Is there some other grammatical issue you have... it is kind of meandering, but that's taste more than grammar.

What would you suggest instead?

To me it reads like a demand: "Valve, open source the Steam Machine e-ink screen"

If we are talking past tense, "Valve have open-sourced.."

And if we are talking American "English," then "Valve has open-sourced..."
