How do you know what kind of technology an advanced civilization would have? and what their limitations would be?
I didn't say anything about the type of technology an advanced civilization would have. The strangeness of these FRBs is discussed at some length here - including why some say "...there is something really interesting we need to understand. This will either be new physics, like a new kind of pulsar, or, in the end, if we can exclude everything else, an ET...." For whatever strange reason, the number 187.5 appears to be involved.
Except radio waves travel at the speed of light - and a signal from an FRB that is over a billion light years away has been traveling toward us for that amount of time.

In your first link from the 'New Scientist' it states: "A more likely explanation, Hippke and Lerned say, is that the FRBs all come from somewhere much closer to home, from a group of objects within the Milky Way that naturally emit shorter-frequency radio waves after higher-frequency ones, with a delay that is a multiple of 187.5". The original article stated the signals came from 1.5 billion light years away. However; our Milky Way is only about 106,000 light years wide. It almost sounds like they are clueless although they did explain why that could happen. That is a big discrepancy in distance. Of course even one light year is way too far for most of us to imagine!
If they are right about the source in our galaxy; it would probably mean that it is even closer than the distance across our galaxy. We are not on the edge of our galaxy and the signal probably did not originate on the edge of the galaxy. Just playing the odds!

Even if they're much closer in the galaxy, the explanation is -- still weird. Why 187.5? In other words -- probably more than one unexplained mystery here. They're found 20 some FRBs to date, my guess is more will be found over the next year which may shed some light on what's going on with these things.

The problem is, we probably wont be privy to everything...
just some examples here...what if a highly advanced civilization sent us details on how we could extract pure energy from some simple process, suddenly no one needs to buy fuel for cars, power for their homes, etc etc...
Or if they sent us details that conflict with our known history. modern 'morals', etc. such things would be disastrous for the public to hear.

Of course; all aliens are good aliens and only want us to succeed - I don't think so. Life is about survival and that would be their major quest if they are wasting energy to get to us. I just don't buy into: Humans are bad and aliens are good.
However; did you see the movie 'Contact" with Jodie Foster: https://www.imdb.com/title/tt0118884/. In that movie we received the instructions to build a transporter and Jodie took the trip. Of course we trusted them (the unknown aliens) not to do anything wrong. Jodie had her God experience and was returned home unaltered (but was she unaltered)?
Let's pretend that AI does surpass us and does take over. We could be left with robots/computers that only quest for more knowledge and they do not care if we live or not. One of the easiest ways for them to spread across the universe is if they piggyback hidden code in messages. Those messages could look like free alien technology and a gift to civilizations like our own. Ideally their signals could be spreading their civilizations at the speed of light; if they found enough suckers.
Our world is too big for one government to hide everything; especially when it comes to signals from space. Somebody else in another country would raise their hand and say: Look at what I found! Look at our kids today and how they cannot eat a meal without sharing the pictures with their best friends and the rest of the world!

I have problems believing they come from some far off place, like another planet or system.
Granted, there very well may be civilizations that DO exist on other planets and in other systems, but I dont think that is what 'UFOs' of the past or present are, their behavior/actions doesnt support that imo.

What behavior, what actions? Do we really know which ones are aliens and which ones are our governments? Then toss in all of the eventually 'explained' sightings and we do not know anything. We do know enough to be confused!
