"There is an idea floating around that uBlock Origin is a lesser branch
relative to uBlock <https://directory.fsf.org/wiki/UBlock>.
The current reality is that there are two branches, not an official one
and a lesser one. I keep developing my branch the same way and in the
same spirit I have since the beginning of uBlock in June 23, 2014, so in
substance uBlock Origin is the original uBlock." - Raymond Hill

As of May 2015, "uBlock Origin" continues to be actively developed and
maintained by founder and lead developer Raymond Hill, but he has
withdrawn his support for "uBlock", citing "serious incompatibilities in
the spirit of the project". The "uBlock" version of the software has
seen little development since.
