All this talk of Cracking software will just cause the original developers of IBrowse to withdraw completely from the community.
If the IBrowse developers do not wish to sell the software any more, that is their right.
I think instead of threatening to crack the software if they do not re-release it, perhaps you should ask them instead of release the source for IBrowse under an open source license. That way other people can pick up the code and keep working on it, and the original IBrowse developers will still retain credit for the work they've done so far.
