Since product development is an ongoing process, companies get a lot of practice doing it. Practice makes perfect when it comes to technology. But when it comes to pricing, most companies get much less practice. Pricing is often an event, a project milestone, something you complete and then forget. Pricing is the root-canal of software marketing.
Vendors change their price lists every year or so, mostly in response to competition.
The exposure people get to competitor's pricing and internal pressures often leads to inappropriate pricing or licensing terms. Most vendors must make very complicated pricing decisions with a limited experience base and with poorly developed internal pricing processes in place. Sure, your company can play follow the leader. Unfortunately, the leader often doesn't know what they are doing either. In some cases, the leaders may be following you.
