Clearly you don't know French players.
Any French player that says they hate the Exchange Variation is a complete fake!
The Exchange French, which avoids the closed, blocked position, is the easiest line to play as Black. All it takes to master the Black side of the Exchange French are very basic defensive moves and strong knowledge of minor piece endings.
I myself have switched to the Petroff, but the Petroff can actually transpose to the Exchange French (1.e4 e5 2.Nf3 Nf6 3.Nxe5 d6 4.Nf3 Nxe4 5.d3 Nf6 6.d4 d5 - this is a direct transposition to the Exchange French - 5.d4 and 5.Nc3 are stronger).
So don't just think that French fanatics love blocked positions. The Advance and 3.Nc3 are far harder to defend than the Exchange or Open Tarrasch (3...c5).
So don't just assume French players hate Open positions.
Play an open position and watch French opening players wither and contort.
They hate open positions, they want a long pawn chain in the center, they want the player with white pieces to submit, I say no!!! No submission anymore.
The best anti-french opening is to turn the position into an open one and make the french players suffer.
Suffer french openers!! suffer!!! you are not a real chess player and suffer
