The most significant ethical objection is that financial incentives can corrupt the truth. When a journalist offers money for a story, they inadvertently create a market for sensationalism. A witness may feel pressured to embellish their account, exaggerate details, or even fabricate events to ensure they receive payment or to increase the "value" of their information. This undermines the primary goal of journalism, which is to provide the public with an accurate and verified record of events.
Journalism relies on the independence of the reporter. By paying a source, a journalist enters into a business relationship with the person they are supposed to be covering objectively. In the context of legal proceedings, paying a witness is especially perilous. If a witness receives money from a media outlet before testifying in court, their credibility can be easily destroyed during cross-examination. Defense attorneys or prosecutors can argue that the witness's testimony was "bought" or influenced by the desire for profit. In some cases, such payments can even lead to mistrials, contempt, and tampering charges.
I know all that (the moral argument)... what I meant was: paying someone in this case might make sense. That is, if said payment/transaction resulted in something useful. It hasn't, sadly, from day one.
Back in 1996, with no internet, most people that watched TV believed anything they were told (no kidding). I remember that lebanese girl who gained worldwide fame for "weeping" crystals of glass (Hasna), the "Alien Autopsy: Fact or Fiction" (1995 "pseudo-documentary")... all those things once showed, would not be questioned the way we do today - AT ALL.
It has been said Vitório Pacaccini paid R$ 5000 back then, for one guy. That would be probably enough to buy a car - in 1996, the Brazilian real had parity with the U.S. dollar. So, US$ 10K in today's money. Did he recover from said investment? Because despite UFO enthusiasts grifting like crazy now, you wouldn't get rich from similar scams/ufology decades ago.
It doesn't make a lot of sense this happened, too, for one particular reason - these people spread their "hearsay" / "anecdotal evidence" (which we all know it's useless without something else to back these up, so they need to give something else worth, a clue that pans out, even if it leads to another dead end after further investigation) with their voices and image distorted. Anonymously (same for one woman at the hospital, check one of the "Fantástico" TV show episodes). So why pay a fortune for an unknown person, when you can do it for free, or much, much less $$$$$$$, with a nobody?
Look at this statement, also from this case:

That was 2 years ago. We don't know who this old lady is (and she may have good reasons for hiding, not saying this is 100% bogus). So even if what she is saying (that saw the "creature" from a small photo?) turn out to be true, what makes anyone think this story could not have been made up? No one except her can answer. And if there's secrecy surrounding the people involved, why would you believe (for a second) none of them would be threatened to change their versions? People don't hide their faces just because they are shy, and hate fame.
That Youtube channel (from Mr. Edison) relies on this and other "amazing" UFO stories every single day. That's how he makes money.
There's also the "tape" (or "tapes") from the supposed creature, something that has only been discussed since... years ago (I don't remember being mentioned back then), the same for Dr. Italo Venturelli, a neurosurgeon from Regional Hospital, that claims that another physician showed him a video of the Varginha alien, that he saw the thing from close distance...
What relevance these two (the old lady and the doctor) have for this case? None, so why (let's assume someone paid them both) their collaboration would be worth gold? It didn't advance one bit believing the entire case, neither the "debunking".
Now, if we had said tape, and someone anonymously got money for the footage, that would lead us somewhere (or not, as I always point out, such records will always be branded as faked, no matter what or when they were created).
Unless any palpable evidence can be presented, this whole thing is no more credible than Bigfoot (perhaps much less, at least for the latter we had an image).
It doesn't matter, in the end, if they show their identities or not. What they claim it has always been a secret, continues to be one, or it's all a collection of made-up stories, that were spreading like the Corona virus.
