I can certainly sympathize with the OP here. Confrontations can be intimidating, particularly if there were 2 or more Hertz employees involved. Just because YOU might feel comfortable confronting someone in this situation doesn't mean that everyone is, and you certainly should not blame someone for not confronting others, particularly in this day and age when people have been shot for less.
I'm one of those that tend to avoid confrontations, but there was a time in the summer of 2021 where I actually couldn't stand back...well, I was trying to "passively" confront the individuals, although they confronted me and it did turn somewhat heated (at least on their side). Here's the story:
I had pulled into a 4-stall Electrify America site just as a car that was obviously some kind of prototype was finishing cloaking their vehicle with a car cover after having just plugged in (stall #1). They secured the cover with a lock and then left to have lunch in an adjacent restaurant. One of the 4 stalls (#4) was down (!) but I was lucky enough to get the last one (#3) available as there was someone at #2. I had my own troubles with the stall I was plugged into (getting very slow charge) and waited for #2 to leave. He and I talked about the people in stall #1, that it was a Nissan Aryia and that they specifically told him he was not allowed to take pictures of the car.
Anyway, I move my car to #2 as someone else pulls in and plugs into #3, and a queue starts to form, including a family with a baby in a Mach-E. I need to get close to 90% to make the next leg...the Bolt is obviously charging slow...and we can see on the screen that the Aryia is filling right up to 100%, which is taking forever.
So just as the Aryia is about done the three of them come out of the restaurant, remove the car cover and unplug the car. I respectfully don't make a fuss and start taking pictures based on what the other guy told me, but I do take a look figuring they will be driving off soon. But no. They get their computers out and are sitting in the car doing who knows what, refusing to move out of the stall. For 5 minutes...then 10. Finally I start to get upset because the poor family in the Mach-E has been waiting for probably 15-20 minutes at this point.
So I ask them if they could move their car to the adjacent parking spot to free up the station for the Mach-E, but they refuse, stating they have their "procedures". After a few more minutes I got sick of their rudeness and decided hey, I'm going to start taking pictures of their vehicle, and maybe that will get them to move.
Well no, that's not exactly the reaction I got. Instead, they start yelling at me and telling me I can't take pictures. Keep in mind we are out in a public space, and I told them that I can take a picture of whatever I want. So they get on the phone with their manager and explain that someone is taking pictures of their car. I ask if I could talk to the manager to describe the situation and ask that he tell the crew to move their car as they were blocking the charging station. Of course I had to stick my head practically inside the vehicle to talk to them, so was able to get some nice closeups!
I tried to keep it relatively calm, but these people were really starting to get aggressive and yelling at me, but by now I felt that I had to stand up for the family that was waiting.
The manager did explain that their procedures prohibited them from moving the car until they entered whatever data they needed to enter. I told him that he needed to fix his procedures, or automatically transfer information to their laptop (it seemed like they were manually entering some data into it), or do something so they didn't occupy a valuable stall for 15-20 minutes beyond when they were done charging. I further explained that it was a public space and I can take whatever pictures I feel like taking, and that if they didn't want pictures taken of their vehicle they should keep it on private property.
I ended up leaving before they did, but at least the Mach-E was able to get a stall at that point.
