Is "The Murdaugh Family Murders" podcast an exercise in public relations?

There are 2 podcasts out there, Mandy Matney's excellent "Murdaugh Murders" and "The Murdaugh Family Murders" that are starkly different. In one, Mandy is out there, boots on ground, digging up as much as she can and asking questions. In the other, the guy (I can't remember his name, nor his co-hosts, and I don't particularly care) seems to use all his time and effort explaining away the questions being asked and the people involved's behaviour. The vast majority of this podcast seems to be dismissive of everyone's concerns. He spends no time digging into things, speculating or theorising and all his time whitewashing what we do know. There is a vast contrast between his "reporting" and people like Mandy as she questions people's behaviour and he tries to normalise the behaviours we find questionable.

We know Alex hired a PR firm, so I suspect this podcast is a product of that. I listen to podcasts all day at work, every day, and the thing that I find the most damning is that all podcasts, bar the most amateur, have some form of on air revenue raising. Either sponsorship, advertising or E-begging, but "The Murdaugh Family Murders" has none of these. I find it very odd to listen too because it's such a big part of every podcast, yet is completely absent here. They hardly even try to self promote either, which is also odd for a podcast. They aren't trying to raise revenue and they aren't investigating, so what is the point? They only seem to exist to explain away and minimise the questions and observations of others. Is their only purpose to feed us propaganda?
