perhaps it was a signal sent out to communicate to others in their own galaxy and after all these billions of years it has just happened to reach us in our own galaxy.
Regardless if the signal comes from an intelligence they are either long dead or so advanced they might as well be incomprehensible gods to us. Maybe if they are still around they regard that radio signal in much the same way as to how we regard the cave paintings of our ancestors.

I totally agree with this, there has to be life out there, its a mathematical certainty.
The only thing that we wouldn't know is what kind of life is out there, there maybe planets where just bacteria lives, just animals, creatures similar to ourselves or as the word "alien" suggests, something that is totally Alien to our comprehension.
What people seem to forget sometimes, is that life evolves and adapts the environment that it evolved within. Imagine there are other similar humans out there, but they developed on a planet with 1.5x the gravity we have on earth. They would look very different to us and would struggle if they were to land on our planet with the difference in gravity. There maybe a planet where there is life that isn't based on breathing in or recycling oxygen, it maybe a different gas or none at all! It all depends on the environment.
Its interesting to ponder...

why don't they send data encoded in the FRB
That's what I'm suggesting.
Maybe they have and we just can't see it.

If it's "them", why don't they send data encoded in the FRB?

Well, I suppose you couldn't rule that out entirely, but what are you proposing is going to block a signal of that strength every 300 milliseconds ?

The light speed barrier plus the exponentially increasing amount of energy required for mass to get near it, implies that we're in an artificially built "universe" which is a model not intended for Star Wars style space travel.

I'm not sure that the light speed barrier in and of itself implies we are in some kind of matrix style artificial reality. I know this is a somewhat poor analogy but for race cars to go faster they get a more powerful engine and cut weight. The physics of the barrier makes perfect sense to me, it sucks but seems perfectly logical. The faster you go the more fuel you need, and then you need more power to make up for the extra fuel.
The only reasonable way to travel those distances would be to bend space time, a wormhole type of thing. But you'd need more energy than our sun released in most of it's lifetime. So either way we're screwed.
If we really want to explore and colonize the Galaxy with humans we would need to do something like the 10,000 year starship idea. But by the time we learn anything who is there to report it to.
