Like everyone, I want more freedom, not less: the battle should begin with a sane GPL version 4. See the MIT, BSD and LGPL licenses which provide more freedom over GPL3.
There's no benefit from making the GPL into something like the LGPL or MIT/BSD. If you prefer those licenses, they're already available to be used instead. The GPL stands for a specific kind of freedom and should continue to stand for the same, maybe with tweaks but definitely in the same spirit. If it continues to go out of fashion then that's a different issue, but watering it down doesn't help to further the cause…
If it continues to go out of fashion, that means that it is not an effective means of furthering the cause ths FSF set out to achieve for it.
One can agree with what the FSF overtly claims its goals to be, without believing that the current form of the GPL is particularly an effective method at achieving those goals in the current environment (one might even believe that the basic approach of the GPL was the most effective approach for an earlier time with different circumstances, without believing that it is effective now.)
It may be the case that compelling very specific rules for software freedom if a package is used isn't actually the most effective way, in practice, of promoting software freedom.
