One advantage a new investor has over someone who provided Spotify with Seed/Series A is greater diversification. Suppose I'm a VC that invested in Spotify, it succeeded and my 20 other seed investments all failed. My retirement wealth is entirely dependent on it's success in the future - your comment outlines why this is risky. Since I am risk averse, I can sell this to a pension fund who will keep it as 1% of their total holdings and we can both be better off, even if we have the same view of the company's likely success in the future.

Of course, if everyone has too optimistic a view on Spotify's future success (could well be the case, I don't have an informed opinion) then buying the stock is a bad idea. But there is not necessarily anything sinister going on when founders/early investors cash out. From Spotify's point of view, they have an inventive to keep these people happy, balanced against the greater regulatory/oversight costs that you highlight.

That can be accomplished with private market tenders though.
