I don't believe they did. This acquisition was by Flipkart, the poster child startup in India, who had a very high bar for hiring. They wanted to interview the non-founders to make sure they met the standard. The founders said you get all or you get none. To be fair, it was a small team of 6-8 employees, so I doubt Flipkart cared. :)
Wait, what are the employee protections like in India that such a deal is enforceable? Why couldn't Flipkart just take them and then fire them a few weeks/months later?
I don't think hiAndrewQuinn was implying that they'd do so, rather, they (appropriately) assume that a for-profit would try to loophole their way out of any obligation, so they wanted to know how exactly the employees were protected.
