The problem is that people overestimate how much they can then eat if they exercise. Runner's World has plenty of posts from people who have taken up running and put on weight. The same happens with 5:2, people think the fasting days will melt the fat off quickly but it doesn't as it's actually only a small calorie restriction over the week.
It does work and very well but not quickly for most people. For the people who want to see numbers dropping on a scale not to get demoralised, exercise can make life harder.
It's best to measure/take pics if you exercise as the contraction from muscle development (muscles being more dense) is a better gauge of progress.
A lot of people don't seem to understand it's better to have a good body composition than be lighter. They just want to see a number on a scale that they've decided in their heads is their ideal weight, regardless of other factors like being older, fitter, etc.
