Sure, but it's still unhelpful to say that overeating is what makes you gain weight when other people eating the same amount and with the same amount of activity are not gaining weight, especially when eating less could cause you to gain more weight until you hit a threshold.
I don't think many people disagree with "If you starve yourself enough your body will eventually start burning fat", they disagree that it's as simple as "anyone gaining weight is necessarily doing it to themselves by eating more than other people".
And starving yourself isn't easy. It's one of the top like five things your body is designed not to let you do. So how on earth is it helpful when people are talking about factors that can influence your appetite and can literally influence the number of calories your body chooses to extract from the exact same food to say "just eat less lol"?
I might add that overwhelming research suggests that social pressure on people's weight causes people to gain weight. So even if you were right, bringing it up would be counterproductive.

That's part of the "calories out" side of the equation, that few people put in the effort to find (if they even know how). And I've found online estimators aren't very useful here, you need to find it for yourself - they say mine is around 1600 when it's actually more like 2200.
Ignoring half of CICO just because people only like talking about CI doesn't make it false.
It's even harder to change CO than CI, that's why people talk about CI. You lose a bit over 100 calories per mile run, and then you have to not compensate by eating them when you're finished. Everyone has a different metabolic set point for how many calories they burn, true.
No one said not eating is easy, especially when there's a lot of food around! I struggle with it. The laws of physics are not kind.
What I will say though, is if I exercise moderate amounts, it makes appetite control easier, at least for me. YMMV. I believe this is because insulin is more level throughout the day.
