The sibling comments are incorrect, the minimum security prisons are called 'Federal Prison Camps", the colloquial name is 'Club Fed'. There aren't a ton of these facilities, so I can see why other people thought that the camp phrasing wasn't literal. Think military camp rather than summer camp.
Federal minimum security prisons don't have fences surrounding the prison so the only thing keeping prisoners from "escaping" is the extra five years that'd be added to their sentence. They have far fewer guards and the prisoners live in dormitory style quarters so it's far more like adult summer camp than prison (commonly referred to as "Club Fed"). Instead of having services on site they'll often drive the prisoners to a local dentist or doctor, etc.
As they get closer to release or if their sentences are short enough, prisoners can even get work release which allows them to leave the prison during the day to work at a regular job. (I think the GP is confusing work release and parole - the Federal system does have work release)
If you're in Western Europe a minimum security federal facility is probably closer to your understanding of a prison than an American's understanding. Hence Americans describe it as a camp, whereas if you looked at it you might say hey, that's a prison.
It's a prison but it's generally much more open. Prisoners sleep in open air dorms, there are minimal to no fences, there are generally good education and recreation programs and vast majority of people are white collar criminals, the violence is much much lower.
The no snitching rule applies mostly to someone who is already in prison and consequences depend on the security level. No one’s going to kill a snitch in minimum security, worst case scenario is that they’ll be outcasts and get into a fight occasionally.
The majority of prisoners are in prison because of a plea deal, not a jury verdict, so they often have to snitch on their accomplices as part of the plea deal (with severe consequences for lying and omissions). In practice the traditional prisoner’s dilemma usually plays out with everyone snitching on each other and everyone getting a deal because the prosecutor doesn’t want to waste time and money on a trial.

This seems unlikely. Any prosecutor running for re-election wants to score. At least one big fish.
Over 95% of criminal cases end in a plea bargain. Trials are rare and unpredictable. The last thing prosecutors want is their career derailed by a fickle jury and the vast majority of crimes don’t involve a “big fish” worth the risk.
This is actually a term used by the BOP to describe minimum security institutions:
"Minimum security institutions, also known as Federal Prison Camps (FPCs), have dormitory housing, a relatively low staff-to-inmate ratio, and limited or no perimeter fencing. These institutions are work- and program-oriented."
