Once again alleged leaks from 🇵🇱 gov officials allegedly using private mailboxes for work. Assuming leaks are genuine, who did it doesn't really matter - the root cause is negligence of public officials and they are the only to blame 🤷 And they are to blame for both using private email for work, and for using it without sufficiently strong authentication.

In the private sector, especially financial, regulators would be all over company employees sending work documents with private email.
FSA/FCA archives are full of multi-million fines for such violations, even if they didn't end up in a breach.
But not in public sector in Poland - you can send whatever to whatever crappy private email you have and you're a "victim".
Can't say about efficacy of their internal procedures but indeed the published breaches are few and you don't have public ministers private email routinely breached in the UK.
In Poland the attitude where politicians feel like the law is for anyone but themselves is still very widespread, and they are often simply arrogant and poorly educated.
