It's not propaganda.If you take three macines and take them apart and examine the quality it's pretty easy to see who has the better design.
Crown did that and made it possible to educate consumers on what they typically wouldn't look at (frames,drive unit design,one lift cylinder vs two and undercarriages for example) when puchasing equipment.
In this day and age equipment manufacturers need to produce equipment that has good servicability and economic lifecycles.
After that it's up to the customer which way they want to go.
