Your explanation is good and thorough.
I always struggle to know when to use the square brackets. The straightforward answer is to just quote directly where possible. But especially in interviews, someone’s answer may be jumbly, so the most honourable thing to do may be to use square brackets to make it easier for the reader to understand the speaker’s point, but you’re not being misleading.
For example, maybe this interviewee said something like “in the future, it — we might come to see that game development, and games overall, will end up turning out to be player-driven”, which could be straightforwardly shortened to what we see in the screenshot: “in the future, it [will be] player driven”. Square brackets, in the hands of a skilled journalist, can be used to manipulate a narrative through selectively quoting people, but they can also represent a speaker’s point far more authentically and cogently than the literal words.

My understanding is that it’s not necessarily porn addiction that causes this, but a particular style of masturbation that some people refer to as “death grip”. Source: a friend of mine who used to masturbate every night before bed to sleep better, but this began causing issues with his partner due to ED. He eventually solved it by using a different grip while masturbating.
In short, if you feel like you’ve come away from this conversation with things to reflect on, then that’s great and I’m glad about that. However, “porn addiction”, as a term, describes a whole bundle of stuff that is still pretty poorly understood, because it can be hard to discern between symptoms and causes
