The Greek claim is entirely reasonable, uncontroversial and correct according to the UN Convention on the Law of the Sea. These islands have been continuously inhabited by Greeks for millennia. The border is drawn exactly according to the proximity to land.

It's not some artificial pile of sand on a bank that will erode away if you look at it wrong, or an uninhabited atoll in the middle of nowhere, first discovered a century ago.

I can't believe I'm reading someone earnestly disputing Greece's sovereignty on HN. Either there has been a lack of information or we're dealing with a case of rampant chauvinism and historical enmity.

You should overlay the Greek EEZ on Japan's or China's claims to see how little it really is. Take a look at the US, UK and France in the Pacific for god's sake!
