This news release (and especially its title) seem/s to be misleading.  Removing the initial singularity is a separate issue from actually removing the Big Bang, which occurs *after* the initial singularity whether that singularity may actually be present or not.  Figuring out a way to remove the initial singularity has always been a goal of most of the cosmology community.  Even other alternate theories that attempt to dispense with the subsequent inflation still have the rest of the more subsequent hot Big Bang remaining in the theory.  The time scale of the hot Big Bang is far longer than the time scale of inflation (~10^-35 s) and the so-called quantum gravity era attempting to remove the initial singularity (~10^-43 s).
