I don’t have inside info like you might, but it seems like a mean-spirited comment considering ebay.com uses marko, as well as other sites in the ebay group.

It definitely has not gained a lot of traction outside of ebay but there is a fair amount of buzz around the marko6 release with a completely new tags-based language.

It is also one of the few frameworks that leverage html streaming in a simple way (and has for a long time) and offers islands-style partial hydration out of the box.
