I don't have a problem with this at all. As Josh notes, it makes sense from a business perspective. Slysoft seem to be doing the right thing as well - they've announced the change in policy well in advance, are giving cutomers the opportunity to buy lifetime licenses until a specified date, and have pledged to honour those and previously purchased lifetime licenses in the future. This stands in stark contrast to how Collectorz handled a similar decision recently...
