They have always been! You could at least have the dignity to read Stallman’s writings (a fine start is available at: https://www.gnu.org/philosophy/essays-and-articles.html , a more advanced diet is available at Stallman.org ) to understand just how politically charged GNU, the FSF, and Stallman have always been.
So now some members of a social movement disagree with the leader of that social movement you feel upset to see social issues discussed? That seems dishonest.
Why should any social and political movement remain beholden to one original star of the old guard as the world moves forward.
How ought the community respond to a trend to controversy and irrelevance other than by asking Stallman to step aside from the figurehead role? Is the argument here really that once you are a figurehead for a social movement you earn that position for life? I can’t think of any successful movement or organisation for which that has been the case.
GNU has always been political, the politics needed to bring software freedom to all users is different now than it was in the 90’s. Some battles have been won, others have been lost hard, new battles have arisen. An honest discussion of whether Stallman is best placed to lead those new battles is overdue.
