Total cost of ownership for malleable software is higher than for something you pay someone else to specialize in modifying, and businesses have gradually learned this. They increasingly realize that software shouldn't be their core business, especially if it's applicable to more than just their own industry. So this is just the normal tinkering -> specialization dynamic seen in most new technologies.
