Well for one thing, the article comes from the tech site with is an arm of an Israeli newspaper. Maybe it's more like The Delaware Herald starting an article off with "Joe's Consulting, a company headquartered in state capitol Annapolis.."
There is to me something negative implied in being a Delaware corporation (tax avoidance). This article is only critical of the shady tactics of the two firms mentioned in the story, not of the existence of Israel. It's not a dog whistle.
