They won judgment for $2.9 million at the District Court (trial) level on the facts as laid out in the Circuit Court decision. They lost two of their causes of action but won on the remaining three - the largest being IIED. That was reduced to $2.1 million due to MD state statutory tort limits prior to appeal. The 4th Circuit reversed the judgment, yes. Their reasoning is laid out in their opinion. That reversal is what the SCOTUS is deliberating as we speak.
I submit it's not that people don't care, but that the facts and procedural status on this are confusing for most people. It's technical, and let's face it - not too many people are either legally trained or enough of a Court afficionado (or weenie, if you prefer

) to dig into the documents and the arguments and really understand what's going on here. The media doesn't have the time or expertise to explain it all in all its nuance and complexity, nor would it be profitable for them to do so. So they oversimplify to the point of being almost or actually incorrect.
You were under the opinion it was already decided at the SCOTUS level from the info out there in the media, after all. I don't give them a free pass, but on these sorts of issues you really need to go to the source to get the full story. They're not going to give it to anyone, they simply aren't equipped to do so. I think if more people felt comfortable that they understood it there would be a lot more folks engaging in the argument.
