The point is
1.
So soon an anomaly is discovered the cause of it can also be equipment failures.
Depending on the anomaly, yes. The vast majority of the anomalies that I know of are either hardware or software failures.
2.
The is problematic because as i read it, staff is not allowed to speak completely open about it.
Yes. For example, satellite manufacturers aren't enthusiastic about telling the world about all the problems their spacecraft have encountered. Commercial satellite operators don't want to provide data to their competitors. Military operators don't want to let potential enemies know about weaknesses in their systems.
And this is problematic because new spacecraft are built without learning from the problems of previous spacecraft, so the same problem may occur over and over even after it's been resolved.
Not really relevant to GPS nav, though.
3.
I cannot find anything thing that say that a GPS staff not is included that kind of politic.
Oh, as far as I know, GPS isn't any more open than anyone else about the root causes of the occasional hardware failures. But they don't have any way to cover up any orbit anomalies even if they wanted to. Every spacecraft continuously broadcasts its raw clock output without any corrections or adjustments, so there's simply no way to hide an orbit anomaly.
