The A Shares issue is fabricated by a select few with narrow self-interests. It is a red herring. Companies such as Facebook, Microsoft, Alibaba -- and other companies that are controlled by their CEOs' voting power -- have no problem attracting institutional investors. Plus, future dilution is strictly limited by the agreement with ECAB.
The Oslo exchange permits the A Share structure.
I too am weary of the tiresome litany about the A Shares.
