The period you're describing was several years after Marco left. And besides, David was technically the sole "founder" (see e.g. [1]). In any case, David was ultimately responsible for the product direction.

I don't mean to minimize Marco's contributions in any way, as his efforts were absolutely massive and utterly essential to Tumblr's success. But with respect to the community and culture, product direction matters a lot more than the backend implementation in this context. (And I say this despite being one of Tumblr's first backend engineers myself!)
