Ashur points out the reasoning here just before this statement: 'I would also like to point out that including an algorithm because "it's better than nothing" result in something that is not better-than-nothing, but stands in the way of good solutions.' and 'From the end-user point of view when they get something bundled into Android, they don't know that it was included there as something that is "better than nothing". They think of it as "good enough; endorsed by Android/Google/Linux". What you give them is a false sense of security because they don't know of all the question marks surrounding Speck (both technical and political).' Edit: also some very good comments in there along the lines of 'why not use AES?', and that the problem that Speck is solving might not be with us for very long.
