Well, they weren't really, the last count was approx 20K coming in from intrusive ads versus 180K I think it was outgoings.
So ads and still burning 160K is not quite sustainable in my book.
I didn't mind the ads so much as the way they were implemented. If you use a mobile version of Steemit.com the page is quite unusable at times, jumping around whilst loading them leading to a frustrating UX.
I would much prefer the deep pockets of Tron to take em away. But hey. who knows what will happen in the future.
