One doesn't move to Delaware simply to register a company there.

No, because there are very good reasons to incorporate in Delaware. I would infinitely prefer to try to sell or get investment in a Delaware C corp than I would in an Estonian company, even if it didn't involve living in Estonia. Getting sued by patent trolls is just such a minor consideration in founding a company, it's not even worth thinking about.

They don't move to Delaware, they just file paperwork there.
