I mentioned in this or another thread that all business exists within a boundary space created by government regulation and oversight. So as a company grows at some point their primary business becomes government and regulatory lobbying. That makes the D.C. region a shoe-in for at least one "HQ'.
You can see the big US tech companies are really starting to reach the peak size where their brand is becoming impaired by their need to convince the public and government that they aren't robber baron monopolies. Like remember when Walmart and McDonalds were evil? I would say Google as an example is now probably approaching more evil than Walmart and McDonalds in the public eye but still less evil than Exxon or Goldman Sachs.
In the next few years big tech might even flip to most evil status although they are fighting back. Amazon is a "peoples" company who supports their workers and pays excellent wages or so their recent PR marketing campaigns tell us right
