Why shouldn't you make changes to Marketplace modules?

Making changes to Marketplace modules is discouraged primarily because updating to a new version of the module will erase your changes. Marketplace modules are designed to be updated periodically to provide new features, enhancements, or bug fixes. If custom modifications are made directly to these modules, those changes will typically be lost when you decide to upgrade to a newer version.

By utilizing Marketplace modules as they are, you benefit from the continuous improvements and support provided by the developer community without the risk of losing custom adjustments. Instead, it is advisable to extend or customize the functionality with custom modules or through configuration options that do not directly alter the original Marketplace module. This way, you maintain the integrity of your application's functionality while still being able to upgrade when needed.
