I feel like this is another topic. What Linus is criticizing in the part you cite is the "or later" mechanism, where as a licensee you can take some program licensed under "License version N or later" and release a modification under "version N+1 only", preventing the original authors to take back the modifications. I understand (and sympathize with) the intent of the "or later" mechanism, and why Linus does not like it (and agree with him). He also thinks the FSF wrongly took advantage of the "or later" clause by releasing a new version of the GPL that is not in the same spirit and he thinks that this is sneaky. One can agree or not.
This "or later" mechanism seems like it would hold in court, contrary to the discussed clause (deemed invalid here) that prevents an author from adding a restrictive clause next to the base license. Hindsight is 20/20, but it does seem like the authors of the AGPL could have anticipated this court decision [that author have all the rights to impose all further restrictions they want withing copyright laws and license authors cannot do anything about it] and don't put this clause, or just clearly write that licensees cannot add further restrictions to the original license.
I would not put the two points in the same bag.
