網路開發人員向來視下一代網頁標準，即HTML 5.0為實現「Open Web」理想概念的不二指南。
這「Open Web」大勢所趨，甚至包括微軟，以及其研發中的Office 14。
Sure. So I mean, to the extent that an improved HTML standard accelerates innovation and consistent reach for web content, we’re very supportive and clearly from the perspective of our tools, we will support the creation and management of HTML content to the level that they want.
I think it speaks increasingly to the realization that rich Internet applications and delivering engaging experiences is increasingly important to all of our customers. I think the challenge for HTLM 5 will continue to be how do you get a consistent display of HTML 5 across browsers. And when you think about when the rollout plans that are currently being talked about, they feel like it might be a decade before HTML 5 sees standardization across the number of browsers that are going to be out there.
So clearly supportive in terms of making sure as HTML 5 is evolving that we will support it in our web authoring tools but from the perspective of continuing to drive Flash and innovation around Flash and rich Internet applications, we still think that actually the fragmentation of browsers makes Flash even more important rather than less important.
HTML5 規範的共同編輯，同時也是Google員工的Ian Hickson作了這樣的回應：
They're single-vendor solutions [and] they don't really fit well into the Web platform,
It's always a problem when you're stuck with a single software provider -- what if they decide to abandon the product you're using? What if they decide to start charging? With an open platform, there's no such risk, since we have true competition, many vendors, and an open standard that anyone can implement.
It would be a terrible step backward if humanity's major development platform [the Web] was controlled by a single vendor the way that previous platforms such as Windows have been.
