Taking Red Hat for granted
I see a number of complaints that RH is not acting in the spirit of the GPL, maybe that's true. I feel, however, that people are forgetting just what Red Hat means to FOSS and Linux.
RH has gone out of their way for years to be a great contributer and promoter of open source and linux. They have gone above and beyond all that is required by the GPL to contribute their developments to the community at large. They built a great business on this, through licensing and support costs, and even with their licensing model, they've still gone out of their way to make RH fully available to anyone who wants it. Now, they seen a trend where their efforts are being taken advantage of, and it's hurting their business. RH took appropriate actions to counter this. There is nothing in the GPL that says you have to provide a detailed change log, and documentation. I think you'll find that most FOSS projects are severely lacking in documentation. RH took action to try and stop competitors from hurting their business through some shady means. RH has acted very much in the spirit of the GPL, but they are hurting because of others who are not, and who are instead trying to take advantage of RH's openness and good participation. They have been put in a position where they are forced to stop being so open for the good of their company, and the action they've taken falls in line with just about every other FOSS project out there.
How are they being so terrible? The criticism is akin to complaining because your neighbor stopped mowing your lawn and shoveling your sidewalks for you.
