No, you're just mad.
Sometimes, people want a certain type of aesthetic or gameplay style that can be achieved by drawing inspiration from previous iterations of an art form. Super Meat Boy is a perfect example, as are the great many games that draw upon the "retro gaming" visual style. Most developers weren't lazy in using that style, they were just looking for a certain feel that could be achieved through it.
The same concept can be applied here. There are areas in maps that lean heavily on their command block-driven gameplay, and when those areas are properly designed around their command block gimmick, they work. When an area is designed around vanilla mobs and pure terrain manipulation/traversal, and it works well, who are you to criticize it? Mapmakers shouldn't be expected to force a custom gameplay mechanic into an area that doesn't need one.
