Its going to get more and more difficult to be flexible as this company locks in their entire development pipeline into a single browser.

It will probably be more expensive to move away from Chrome if you DONT develop for other browsers now. All it will take is the company that owns Chrome deciding to exercise their Terms of Service and Privacy Policies to the best of their abilities. If you sprinkle in support for other browsers now, it wont take as much work when the huge overhaul is needed later.

The money guys are blinded by the dollar signs though.
