Before deciding to license a Creative Commons to a plant, there are a number of other factors to consider. The work must be subject to a Creative Commons license, the licensee must have the rights, i.e. he must own the copyright to the work and understand how Creative Commons licenses work. An important point is that Creative Commons licenses are not revocable; This means that a creator cannot prevent anyone from having acquired the work under a Creative Commons license from using the work in accordance with this license. Of course, they can stop distributing the work at any time, but this will not remove from circulation all copies of the plant that already exist under CC license. In addition, collective management companies that manage rights on behalf of authors cannot, in certain legal systems, allow members to license their works because of the way the author transfers their rights to the collective management company. No two collective management companies are the same. They may vary within the legal framework by which they are created, in terms of structure and exploitation, of the rights they grant. Some collectives do not license at all. Instead, they receive revenue from the sale of photocopiers, such as photocopiers and fax machines and computer hard drives, which are known as «machine distribution.» Collective management companies are generally not-for-profit organizations and are owned by their members, the rights holders they represent. However, in the 1990s, the term of protection was extended by an additional twenty years in many countries, i.e. to the life of the author over seventy years.
This has been accelerated by two of the world`s two largest trading blocs, the European Union and the United States, both of which have influence over the global economy, both of which have influence beyond their borders. In 1993, the European Union (EU) «harmonized» the duration of copyright protection and neighbouring rights, which meant that most EU Member States were required to increase the author`s lifespan over seventy years. In 1998, the Copyright Term Extension Act extended protection to general copyright in the United States and to 95 years for loan works (neighbouring rights). Given that copyright was increasingly in the area of trade agreements and that trade agreements between the EU and the US and third countries were generally needed in the longer term, the dye was paid to many other countries around the world. (For more information, see copyright and trade agreements). Consumer advocates are largely concerned that TPMs/MNs are not able to prevent copying commercial copies, but are good at limiting their use by consumers, including normal planned uses, such as format and jet lag. Consumer choice can be divided into different price models for limited functions versus wider choice. PMTs block support technologies used by people with disabilities.
Lack of interoperability. B, for example, the inclusion of consumers on a platform, can lead to anti-competitive behaviour, price discrimination and market segmentation.
