I don't understand why deadpool is better than acquihire. You would return at least the same amount of money to your investors, but also you could put this as an exit on your resume and get a significant amount of money personally.
From a founder's perspective: If you want a job at AmaGooFaceSoft you can get one whenever you want (we're assuming you're very talented and in the current economy). If you want a house worth of money as a result of working at AmaGooFaceSoft, you can get that by getting the job and then waiting. Most people do not get into startups because they are the glide path to AmaGooFaceSoft careers. People might consider the option value of the next thing, or the certainty that the next thing will not involve a manager and HR department, higher than the (not insignificant) amount of money AmaGooFaceSoft will pay for engineers bought in quantity.
