Multiple things: * disabling Nord Stream I gets Gazprom off the hook for failing to deliver gas to customers in Europe through force majeure * Leaving one pipeline of Nord Stream II intact left a door open for Germany to get gas in exchange for ending support for Ukraine * it's a not so subtle message to Nato that Russia sees the Baltic as their lake, and underwater resources are not safe * planting disinformation about "who really did the deed" was used to sow discord among the de facto allies of Ukraine.
