The ultimate goal is to make anonymous speech online seem shady and suspicious (only trust thoughts from certified citizen accounts) and to make people more cautious about what they write online. Politicians are really tired of being mocked by anonymous people immune to being shamed with the help of the fourth estate (press). This legislation is one piece of the puzzle.

The people pushing this come from the usual power centers in European politics, the (current) centrists. They feel motivated to protect their positions against encroachments from what they consider extremist positions (be it e.g. economic left or right, or a or b on some other scale.)
