This is the French government aiming to have all the government agencies use videoconferencing software that was developed internally by themselves.

So a huge waste of taxpayers money...

This is a pure ongoing cost to develop and maintain (more so than using an market product) while not getting any traction externally. The productive way to do this is to encourage private companies to develop these products and to support them with government contracts. There are not going to conpete with Silicon Valley if they don't create actual private competitors. Absolutely ridiculous approach but unfortunately typical of the industrial scale waste of the French government...
