Can I say that an application is Free for common use? meaning everyone has access to all features and can use it free of charge unless s/he needs to use it on a large scale. This would require a paid subscription Thank you for your help.
Open source means Applications or software that are free for common use.
When people start to use these open source applications for their own commercial purposes, they are punishable by law. It will be clearly quoted in the license file of the application or software.
In the license file(doc file),the creator of the application or the software will specify either of the different versions of licenses say GNU GPL(General Public License)or GNU AGPL or APACHE license or MIT license
So, answers are
Free for common use -> open sourced
To tell them that users should pay when they need to use it on a large scale -> licensed
