It's less what new information has come to light, and more what hasn't. For MERS and for the original SARS, the proximal animal hosts were identified within about a year. For SARS-CoV-2, we haven't found that yet. (See my comment history if you're thinking pangolins; they're pretty much abandoned.)
So a year later, despite the considerable effort spent looking for evidence of natural zoonotic origin, we still have nothing. We also have no evidence of lab origin, but that investigation has been thoroughly obstructed--for example, the WIV's private database of viruses went offline in September 2019, and any reporter who approaches the mine where SARS-CoV-2's nearest known relative (RaTG13) was discovered gets turned away by Chinese police.
