"Encouragingly, this socialistic "gift economy" is still at the heart of computer/software development and the Internet. For example, the Free Software Foundation has developed the General Public Licence (GPL). GPL, also know as "copyleft", uses copyright to ensure that software remains free. "
1) The GPL uses copyleft as a mechanism, while it's possible to conflate GPL and copyleft as one thing, there are other copyleft licenses (Creative Commons -SA) and other copyleft-inspired works. So it's probably more accurate to say
2) "know" is the wrong tense here. Combined with the above leads to : "GPL, which uses a mechanism known as copyleft to utilize copyright to ensure that the GPL covered software remains free. "

#2 is fixed here, 'know' was changed to 'known' by zesty but the first issue here, and my suggestion to resolve it is still valid
