A key disadvantage of proprietary software is that it can be more expensive than open source alternatives. Proprietary software is developed by a company or individual who retains exclusive rights to the software's use and distribution. As a result, users typically have to pay a license fee to use the software. This can be a significant financial burden, especially for small businesses or individuals who may not have the resources to afford such expenses.

In contrast, open source software is often available for free or at a lower cost, as it is released with a license that allows anyone to view, modify, or distribute the source code. This cost difference is a major factor for many users when deciding between proprietary and open source options. While proprietary software may come with certain advantages, such as dedicated support and regular updates, the expense associated with it remains a noteworthy disadvantage when compared to the often more economical nature of open source solutions.
