Why is Ripple's controversy relevant to Stellar? As I understand it (and I may be wrong, I was not aware of Ripple until Stellar), the big issue was that the founders of Ripple Labs allocated 20% of all XPR to themselves.
Stellar, on the other hand, is only holding 5% of STR in reserve, which is used to fund the nonprofit, and already sold off 2% of that to Stripe (who in turn is going to be auctioning off 50% of that). Ripple's approach looked like a pre-mined altcoin thing, but Stellar has a significantly smaller reserve that's very publicly being used to fund the operations of a nonprofit, rather than being used to enrich 3 individuals.
Basically the only odd thing here is that using STR as a source of funding means that they care about the market value of STR, whereas most uses of Stellar don't care at all about the market value of STR but only use it as a medium of exchange. That said, all the Stellar Foundation really wants is for STR to remain relatively stable (which it should), whereas with Ripple's approach there's a genuine conflict of interest as the founders would get personally rich if they could boost the value of XRP (conflict of interest because it's in the network's best interest for XRP to remain stable, just as STR is expected to remain largely stable).
