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.
Thank fuck someone replies knowing what they are talking about.
The last thing Valencia needs is someone putting it as an example of how to do things. Valencia is a corrupt region, and one where corruption is pretty much impossible to eradicate because voters continue to support corrupt politicians election after election, with justifications like "yeah, he stole a lot but he also built a great hospital", and shit like that.
If they moved to linux most likely is because they can't pay for Windows anymore. Or worse - they haven't paid invoices from Microsoft for years and MS is just fed up.
