This will apply to anyone designing with the iCE40 parts, including the iCEstick board.
When I came to do my yearly renewal for the iCEcube2 design software, I discovered that it is now subscription based (previously it was free).
The prices are here

If, like me, you aren't using the parts commercially, there's a e-mail contact link on this page that allows you to apply for a free licence for "hobbyists, enthusiasts, community educators & start-up companies". Go down to near the bottom of the page to where there is a heading of "iCEcube2 Makers Community".

The one exception to all this is the newer iCE40 UltraPlus parts which can also be used with the (currently) free Radiant software.
