What are the costs of using python/R? I'm not talking about the full french gov, but a single division (around 25 workers), for which the procurement is done.
This is in reality a clear cost-saving measure, as you may have to pay one time for training, which is however done by another division of the French State (the statistical body, INSEE), and those career workers don't get bonuses or are paid overtime anyway.
Afaik other "big corps" are moving away from SAS as graduate only know Python/R nowadays, which are better and more flexible tools.
Improving tooling and reducing costs are just a thing for private companies. Yeah, the horse carriage drivers weren't happy when the gasoline engine appeared. Imagine the switching costs! There are still horse carriages around! Horses are reliable! You can drive a car on your own!
