The logical convolutions you have to go through to make Ayn Rand into Hitler are absurd. Marxism has easily killed ten times that number, many by accident, many intentionally, yet few hold Marx personally responsible or would find his face a repugnant symbol of death.
You're allowing your opinion of an ideology to turn it into nazism, but in so doing you must overlook what makes nazism unique: that it does indeed advocate murdering people simply for being different as a solution to problems—and that it actually did murder millions of people directly. Ayn Rand did not do any of that. At worst, she advanced a philosophy whose overzealous application by unscrupulous people with power led to deaths. If that's enough to make you Hitler, nearly every philosopher or novelist is, or would be if they were simply famous enough.
In short: calm down. She's included in the image because her novels are in the 100 Most Influential List put out by some non-profit. Not because she was a saint.

You obviously don't live in America!
By the way, telling someone to "calm down" makes you a douchebag.
And strawmen don't help either.
And let's not kid ourselves: she's in the image because someone in that company is an Ayn Rand fan. There is no shortage of Randists among tech people. Quite a bit fewer among literary types for obvious reasons.

It says a lot about your intelligence that you immediately jump to a worldwide conspiracy theory from a single instance of a single individual putting his personal favorite author in a logo for a writing website.
