The Kivimäki case: 6 years and 11 months for 33,000 victims. Why are Finnish criminal sentences such a joke?

I just read the update on the Vastaamo hacker, Aleksanteri Kivimäki, and it seems a total mockery of justice. The Appeals Court just "tightened" his sentence to 6 years and 11 months (basically the legal maximum!) for the biggest criminal case in Finnish history!

Despite being convicted of destroying the lives of 33,000 therapy patients (linked to multiple suicides), he was released in September 2025 because the court was afraid of having to pay him compensation for "over-serving" his time. Now, his lawyer says he's "abroad" and won't say where. How was he even allowed to leave? And, apparently, because his previous convictions for hacking happened as a minor, the system treats him as a first-time offender and he only serves half the time.

This seems to only encourage more criminality. If one of the most notorious hackers gets off with 3.5 years, I can't imagine anyone will be too worried to follow the law.
