First of all: Valencia is the most indebted region of Spain in relation to it's GDP (and second in monetary value) . Having spent billions on ill-fated projects (F1 track, Americas Cup, Arts and Science City) that have failed to meet economic returns. The former President resigned over corruption charges, Majors being investigated for contract mishandling and enrichment, a former governor in jailed this same week, etc... No thing that comes from this region is out of suspect.
This said, What it is commonly spoken about these projects is that they do not exist to leverage libre/opensource software on the school. They exist to praise regionalism of the different autonomies(regions) of Spain by local politicians, so, instead of viable ecosystems, they become second-choice-dual-boot-distros that exist to fill the pockets of several local companies (distro makers, maintainers, call-centers, certifiers...) that do literaly nothing contributing to the communities they get their software from.
Also, every region spent millions on creating their own distro, duplicating efforts (which is a clear indicator that it is a national-regionalist issue rather than a techno-economical one). If Extremadura has it distro, Andalusia also wants it and Valencia too.
Moreover, I put in doubt the claim that a somewhat high amount of Euros were saved whatsoever because educational licensing is usually done on a gubernamental level and not on a seat level.
So, this is only one more sample of PR-BS for me.
