@ErikUden @knightly666 IBM took this to the next level in the 1990s. They gave out "trial" versions of OS/2 Warp 4 on CD-ROM. The trial version was crippled with the most BS, easy to crack protection imaginable. So much so that many people cracked it and installed the full version *accidentally*. The reason... get OS/2 into as many peoples hands as possible, as IBM made one last push against Windows. Alas, it was not to be, but it shows IBM was ahead of the game in terms of viral tactics (and OS/2 wasn't a bad OS either - "A better DOS than DOS, and a better Windows than Windows" was quite accurate).
