Hi there. While I have not read this particular Margaret Atwood story, I have actually met her in person, and I am well versed in Shakespeare's Tempest, so I am hoping I can still provide some clarity!
Most modern Shakespearean scholars read Caliban against the contextual history in which Shakespeare was writing (not just within the fantasy world where the Tempest takes place). As such, Caliban is supposed to represent "savage" stereotype of native people that Shakespeare's contemporaries would have been encountering in the new world. Caliban's is portrayed as an uneducated, uncultured, rapist who had no purpose before his new master, Prospero, came to the island.
Caliban's role in Shakespeare's theater was solely to make fun of native people - he is largely there for comedic relief and doesn't really add much to the play in terms of the plot or other central themes that are key to the Tempest (such as authorship). His unruly behavior and submission to Prospero gives the play a very pro-colonialism message.
While Atwood may have chosen to take out Caliban for many reasons, his offensive history may be plenty! Margaret is a outspoken advocate for women and other minority folks so I doubt she would skip over this troubling part of history. Hope this helps!
