An ISP is local, accountable to its customers and more important subject to local laws that can be enforced. An added benefit is ISPs cannot collect, collate and correlate vast amounts of global user data. This is a huge win for wider society.
Compare that to unaccountable global organizations built on stalking and hoovering up every single piece of user data with zero regulation and subject to and support of their own home governments.
With this already in play 'concern' with localized ISPs cannot be justified without first offering more immediacy and potent solutions to the larger global surveillance problem.
