Softball is not popular in France/Europe.
However, softball will (most likely) be back for Los Angeles 2028 and Brisbane 2032.
It's not just unpopular, it's basically an unknown sport. And not just in France/EU, but in most of the world. This sport shouldn't be in the Olympics at all.
Regarding breakdancing, there have already been B-boy international tournaments. France often finished first, which may explain why it was recommended for Paris 2024.
