Yes, ut the Jurati Borg are apparently permanently engaged in guarding the wormhole to another realm where a giant elder god resides, or something. They’ve been relegated to the status of a cosmic bung cork.

Well the original Borg are now presumably all dead now, since the queen was defeated and the cube destroyed at the end of S3. The Borg led by the new Queen/Jurati are no longer evil and they are doing their own thing.
