We seem to keep seeing videos of US firefighters ventilating before they have fire control and either having a near miss, getting injured or dying.
Do you have any examples?
I’m a US firefighter, our department doesn’t vent until the engine has water on the fire. And even then we pay careful attention to where we vent. Can’t speak for other departments.
May be a lack of training or inexperienced.
Here’s a few examples:

When you say water on the fire, does that mean that you have fire control (the fire under control) first, or just first attack?
I would agree that most of your examples show poor tactics and/or poor training.
However the first video appears to show proper vertical ventilation. There is a charged hose line into the front door, they are either putting water on the fire already or will imminently.
I’ll cite a UL study on the topic. This paragraph is from the summary, and it highlights the importance of coordinating ventilation with the attack team, but does show that it can greatly improve conditions for the interior team(s)
Here’s a link to the full study, it’s a long read but very interesting.

With that being said, my dept generally doesn’t ventilate residential roofs because the reward generally doesn’t outweigh the risk. And horizontal ventilation is almost as effective.
Thanks for the reference.
I think your snippet proves my point. Once the fire is out, then the urgency is gone. Rather than cause more damage, why not open the doors and windows and bring out the PPV? It also lessens the risk from introducing air if there’s hidden extension.
