I disagree, I think it it more that the future effort vs reward didn't stack up as well. Because so many developers had already purchased and it was well known, a free version 2 wouldn't represent the same kind of financial gain the initial spike did, despite all the extra effort. A paid version 2 though produces a similar windfall again, rather than diminishing returns.
