From a purely profit-oriented perspective, no. They're setting up a pretext to eliminate the lifetime license plan due to a lack of interest. No sane person would pay that kind of lump sum for the service (and the insane ones will bring in triple the revenue), so they'll claim that there is no market for it. After that, they're free to crank up the periodic subscription prices.
Never attribute to stupidity that which is adequately explained by profiteering opportunism.
