I don't know anything about their shareholder distribution at this point, so this is all conjecture. Since they took capital, the funds associated with their prior fundraising rounds ($1.2B total) likely have 10 year horizons. Investors are looking to recoup their investment during that window. Having the company stay private means that they either need to raise a new round to buy out their old investors, or they need to return sufficient profit over a short window (just a few years) that their investors are happy with the dividend. Not to mention, there are tons of advantages in having access to the public markets. It's definitely a headache and work, but it's not without its benefits.
