As long as 100% of the information is true, this is fine. When competing powers reveal each other’s dirty secrets, ordinary citizens win.
But we need to be careful about injection of various messages in a factually correct information: let’s say, 99% of the facts are true, but a certain person or business is incorrectly mentioned as connected to them. It can be a genuine mistake or it can be an attack on that person or entity. This is just one of the many scenarios of using information warfare.
It would be great if a newspaper or independent OSINT team would verify this information.
