Note that they have one Mexican, one El Salvadorean, but no South Americans. Also note that the only African is a Tunisian ex-Google employee. And the only east or south-east Asian appears to be Japanese. Why are we letting this group of business people make decisions about global internet? Why not, for example, scientists from the different countries?
this is a good time as any to remind that the vast majority of the world is under illiberal regimes and religious dictatorships and a "global internet governance" would outnumber free, liberal countries 2 to 1.
you'd need to start putting barriers and borders to the committee to avoid regime using it to steer the internet toward oppressive goals, and there's not one way of partitioning it that would make the whole thing politically acceptable by the countries making the cut and by those not making it. it'll become just another bargaining chip on the international political bickering, at which point competing business interest under a liberal constitution start to seem a more reasonable compromise.
Further, ignoring the global nature of the internet when it comes to the governance of it seems simply unwise, and is very clearly a political decision in itself and not neutral.
It is also clearly illiberal to explicitly deny agency to a multitude of affected stakeholders that have been allowed to join the network, despite their dirty track record.
Whether you like it or not, those "global businesses" do have an internet presence that's unquestionably more extensive than some countries. It would not be fair if organizations or countries that clearly are not interested in having a say on any issue regarding the global internet would have more of a say in these issues than those whose livelihood is the internet.
FWIW, it's said that .int (international) never gained momentum for these globe-spanning organisations.
