This is an idea that I
have been proposing since a while (the first time at the GARR
Conference 2018 in Cagliari):
"Under this system, every company above a certain size, say, those
with more than a ten percent share of the market, that
systematically collects and analyzes data would have to let other
companies in the same market access a subset of its data. "
My argument was that
personal data has infinitesimal value to individual users,
therefore they are quite willing to relinquish it in exchange for what they consider some
useful facility.
However large collections of individual data have a huge value:
but such a value is a collective one. Hence it should be
considered a Commons. As with Commons, they should be not owned
by anyone and cared for by a public organization.
Who invests
in collecting those data should have the possibility to exploit
it according to the rules established by the Commons and
maintain them available also for others to use on a fair basis.
Any entity that reaches a relevant market share should be
subject to this provisions.
