Librecon Q2: Companies transforming and leading this new world, such as Google, Paypal, Facebook, Wikipedia, Tesla or Samsung do not conceive their bussiness development without using open source.Do you think there is no going back on the adoption and collaborative development of open software?
I think, as defined by @rms, freedoms one to three (to copy, modify and fork) is here to stay and the value of collaboration is now firmly part of the technology world.
However, there is still work to be done to further Freedom Zero — the freedom to run a program for any purpose. See https://ethercalc.net/#freedom-zero for a brief discussion.
