No, it is actually both things. The sugar causes people to eat the stuff and does contribute to obesity, but sugar is only a contributer. The additives and ingredients like vegetable oils (which cause health problems of their own due to their chemical structure) also contain a lot of calories (fat contains more calories per gram than sugar).
In Australia obesity increased while sugar consumption decreased. The additives really matter and have a huge impact on human health--they are not a rounding error, but it was a great marketing tactic on behalf of various food industry groups to vilify sugar while deflecting from the other ingredients that are similarly problematic.

Which are present in home cooked baked goods too.
I know it's not as simple as just "sugar=fat" but the difference between home cooked junk food and industrially cooked junk food is vanishingly small.

In terms of chemistry/nutrition I agree. However there is a huge difference in convienence. Pastries are a huge pain in the ass to make, and consequently I only make two or three pies a year. Store bought pastries are trivial to acquire and gorge on seven days a week.
