This was a band that inspired a thousand other house bands, Was there in the early 90s at the start of the House/electronic experimentation in the French underground, got an animated film done by Leiji Matsumoto and won several awards with their album in 2013. So yeah, it's sad to see em go.
As to why they'd break up, Rumor has it that they broke up because one of them was developing health issues with hearing (tinnitus) and didn't want to hold back the other one because of it… which is also why they haven't done anything, neither tours nor new albums, in ages.
Can only imagine how soul crushing that kind of thing is for musicians to end up with.
The movie "It's All Gone Pete Tong" touches on something similar when a DJ goes deaf and has to deal with the life changing consequences, a movie I consider one of Paul Kaye's better works as while he's still the usual arse of a self he's typecast as in things he ends up using that very well as the in character coping mechanism.
