Gnu / Linux maintains and encourages free technologies and Free Code. However, for a time, proprietary software was a necessity for many people. A clear example of necessary proprietary software is Flash, Adobe's web page technology that we need to navigate the Internet.
A few hours ago, Adobe has reported that 2020 will be the end of this technology. For which it is working with various companies to favor other technologies that supplement the operation and usefulness of Adobe Flash.
There are already many users and companies that are working on alternative solutions to this technology. Mozilla offers a choice; Google is supporting and developing Html5 and WebGL; And, many web developers are moving away from tools that use Flash as well as encourage developments that do not need Adobe Flash.
Adobe recognizes that the technology is not being useful and therefore will eliminate the technology next year 2020, although will continue to release security updates for users using this Adobe product. Fortunately, Gnu / Linux and its users have a better handle on this adaptation process than Windows and its users. From the first moment, Adobe made it difficult for Gnu / Linux users to use Flash. This caused various plugins and alternatives to be created. These alternatives continue to work, so once Adobe Flash is finished, Gnu / Linux users will be able to make use of it thanks to these alternatives and continue with Flash for as long as we need.
In any case, the end of Adobe Flash is something that will happen and that will make users more free, unless they can use free code without depending on any kind of proprietary tool or technology. Something that many users will appreciate although we have to say that the development of alternatives is currently helping many users.
