France is not Libra positive, but true crypto positive. They finally issued a law that the exchange of cryptocurrency to another cryptocurrency is not subject to taxes. You pay taxes only from profit when you sell your cryptocurrencies into fiat. 
That is good. Here is the link for that news, https://blockonomi.com/france-no-tax-on-gains-from-crypto-to-crypto-trades/Facebook currently has more than two billion users, more than any other country, and more than 4 times the European Union. Therefore, not only France or Europe, I believe that the governments of many countries feel threatened by Libra. Even so the head of Libra is still very confident that it can make it on time, I look forward to that day.
I don't think that they feel threaten at all. What France say is that company such as Facebook are not to be trusted because they have problems protecting their consumers, and that's why France doesn't like this Libra project at all.
