They market their launchpad software as the solution to develop open source software... I am under the belief open source software shouldn't be built maintained or otherwise dependent on proprietary software.
Fedora also likes to be high and mighty that they don't use proprietary software, but last release they put in a codec manager, to buy fluendo codecs. Which now they are taking out I here. Also they use proprietary firmware like everyone else to get thinks like wifi runing. What's the difference, look I'd like everything I use to be open source. That's why I use linux. But when your just using close software to enable the use of open software, what's the big deal. Your just nit picking because you don't like ubuntu. I hardly think you don't use one bit of close software, between flash, firmware, codecs, and 3d video. What's the difference if you enable it. Or like ubuntu the os asks you IF you'd like to enable it. This is all just bickering and bias nit picking in my eyes.
Using binary blobs(drivers,flash, etc.) to fill in gaps in free software isn't a long term solution. It doesn't help the community to not aide developing free drivers. The problems most people have with Linux whether they use Ubuntu/Fedora/SuSE or whatever is the trials of binary blobs that don't work well with the fast pace of linux.
I'm using both ubuntu and rad hat right now, which I have been for years. So don't be mad for me calling out people just name calling. Childish...
Tsabo, like me and other people have been saying, just pick up different live CDs and see what's best for you. There is a new version of ubuntu and fadora coming out at the end of this April to keep your eyes open for.
Whatever though, these conversations are always endless discussions between users of either distro.
