Government and charity can be corrupted (and usually are, to at least a small degree). Private industry is corrupt bt default: to the extent possible, it will intentionally serve owners at the expense of other stakeholders.
This is not a knock against private industry in general. Capitalism's greatest strength is precisely that it harnesses corruption toward productive ends through private industry.
Nonetheless, it's unsurprising that people would take a chance at less-corrupt versions of key infrastructure. My preference would be to do this through charity, which worked pretty well for e.g. Mozilla for a while - but I wouldn't call other directions naive.
