This is talking about the freedom the band had after Roger Waters left. When they say the wall came down, they mean when he took off because Roger Waters wrote all of The Wall and made a lot of the music. The rest is saying how they're free to do what they want because by the time they released The Final Cut, Waters was doing everything. The album jacket even says "An album by Roger Waters and performed by Pink Floyd." This whole album talks about Waters leaving.
