First, an office less world is a dream right now. If you plan to be hyper-competitive, there's no substitution to 'water-cooler' talk. Technology is nowhere near being able to reproduce that.
Second, why would they put the picture of a communist leader who used to shoot defectors and kill artists? Why is he any sort of hero?
At this point, the Che portrait is sort of the reverse story of the swastika. The swastika started out as a symbol of something good and got turned into a symbol of something monstrous; Che started out as something monstrous and got turned into a symbol of something good. That good being, I suppose, a consumerist, photogenic representation of rejecting consumerism.
Back in high school, kids would wear that image. One day while helping my friend at his family's coffee shop, his coffee supplier - who was making a delivery - told us about how Che's army butchered his entire family aside from him and his brother. I've never looked at that image the same.
I don't know that it's a really great idea to throw Che's image into a page related to your product, just because of how polarizing a figure he is, but I'm pretty sure it's only there as a casual reference to "the revolution isn't dead, by any means," and doesn't really have anything to do with glorifying Che or otherwise calling him a "hero."
I could think of far more deplorable historical figures someone could stick a picture up of other than Che.
While I don't necessarily agree with his ideals, I can respect certain aspects of his persona and drive.
