According to one study, economic competition from different software services leads to EULAs more favorable to the customer.
Resale According to
United States federal law, a company can restrict the parties to which it sells but it cannot prevent a buyer from reselling the product. Software licensing agreements usually prohibit resale, enabling the company to maximize revenue. Proprietary software is usually offered under a restrictive license that bans copying and reuse and often limits the purchaser to using the software on one computer.
Source code is rarely available. Derivative software works and
reverse engineering are usually explicitly prohibited. The issue of reuse is particularly important in the copyright law of English-speaking countries.
Data collection Many EULAs allow the vendor to collect information about the user and use it in unrestricted ways.
Derivative works Some EULAs restrict the ability of users to exercise copyright over derivative work made using the software, such as creative creations in the
virtual worlds of
video games. Although most video game EULAs assert that the developer holds the copyright on any
user-generated content, this is contested by users and has not been tested in the court system. Legal scholar Anthony Michael Catton suggests that user-generated content should be considered
jointly authored by the video game developers and the users. Some companies do allow video footage of their games to be distributed online, even for profit.
License term Traditionally, software was distributed in the form of binary
object code that could not be understood or modified by the user, but could be downloaded and run. The user bought a perpetual license to use a particular version of the software.
Software as service (SaaS) vendors—who have the majority
market share in
application software —rarely offer perpetual licenses. SaaS licenses are usually temporary and charged on a pay-per-usage or subscription basis, although other revenue models such as
freemium are also used. Even if the user purchases a perpetual license, it is common for EULAs to allow unilateral termination by the vendor for any number of vague reasons or none at all. Furthermore, many EULAs allow the vendor to change the terms at any time and the customer must choose between agreeing or ceasing use of the product, without getting a refund. EULAs are also applicable to
in-app purchases and
microtransactions. As a result, players could lose access to purchased content if the vendor decides to terminate their license and withdraw the content.
Product liability Most EULAs disclaim any
liability for harms caused by the product, and prevent the purchaser from accessing the court system to seek a remedy. ==Enforceability==
