An example of a free software license with Copyleft is the frequently used Gnu General Public License (GPL), also the first Copyleft license. This license is intended to give all users complete freedom to use, study, and modify the software privately, and if the user complies with the terms of the GPL, the freedom to distribute or modify the software. For example, all changes made and transmitted by the end user must contain the end user`s source code, and the license of a derivative work must not go beyond what the GPL allows.  End-user licensing agreements have also been criticised for including conditions that impose burdensome obligations on consumers. For example, Clickwrapped, a service that evaluates consumers based on their respect for users` rights, says they increasingly contain a delay preventing a user from suing the company.  Payment of license fees is generally provided for in the Software License Agreement, unless the license is a one-time payment made prior to granting access (e.g. B if you buy a software or video game CD at the helm of a retailer). For many years, most software has been sold this way. However, the most common model today is a subscription-based system, in which the software license is granted for a fixed period of time and subsequent access is subject to future additional payments. This is particularly the case for software as a Service (or “SaaS agreement”). In recent times, publishers have started encrypting their software to prevent a user from installing the software without accepting the license agreement, or violating the Digital Millennium Copyright Act (DMCA) and his foreign colleagues.

In addition, insurance rules are important when the software provider will have its staff delivered to the customer on site.
This is a certain type of liability risk that may need to be treated in the same way.. . . .
