I'm sure this has been pointed out before, or if not, should have been.
If those barnacles are genetically modified lifeforms designed to produce meta-alloys, or has been speculated a method of "growing" ships underground, then they are not free booty for any passing stranger to help themselves to. The owners of said barnacles is going to take a dim view of the (as they would perceive it) theft. If..and it is an "if" at present, the barnacles belong to the same race as the owners of the artefact and probes, then we have been giving away the location of bases (via "bombing" bases) and showing off the fact we have been using the meta alloys for engineering our ships by actively seeking alien interdiction after possessing the probes etc.
Also, if ED lore is correct, we also tried to exterminate the Thargoids.
It's all a bit Jack and the Beanstalk we've robbed, possibly committed ecological vandalism, trespassed (if the latest trailer is anything to go by, that's not a human base), and we are going to pat ourselves on the back and hand out medals if we defeat said aliens.
I'm not saying that we should hand back all materials and say sorry, I doubt the devs are going to let that happen, and it would make for a dumb game, but I just want it registered that we are in all probability not entirely the good guys, and morally we are on very thin ice. The cry of "Hey! we didn't know they were yours!" just ain't gonna wash.
Personally, I think when the aliens do get all frisky, the rush for solo-play is going to be server breaking
