btw I have a Communication Studies/Advertising degree and work as a front-end developer, so no, that doesn't sound easy to me ;)
Building, marketing and running a company is a different specific skill set.
How is that not division of labour?

Presumably a lot easier than building a vacuum cleaner.
If I had the means to build a vacuum cleaner (not that hard, you know software can be way more complex than that), but instead sold my project to Dyson, because they have the means to produce and market it, yes, I'm setting myself up to be exploited. It's an option. (drifting off-topic, but crowdfunding is changing that too)
Also, where is the evidence of exploitation? Does this guy make more money than he would if there was profit-sharing? Paying a salary is profit sharing.
This sounds strangely familiar...
Yes, this is called the division of labour. When not everybody has to know how to do everything, more things can be known and more things can be done.
Making a marketing plan and a website sounds easy to you, but why don't you argue that they are being exploited by the vacuum cleaner or detergent manufacturers' economic and knowledge advantage? Probably because designing and building a good vacuum cleaner or formulating an anti-allergenic organic cleaning detergent doesn't sound easy to you.
