So many things I want to say...
None of which I can here.
At the end of the day, we really don't know anything about Thargoid technology. They certainly could be doing something to "our" space to make it more compatible.
Star Trek's Species 8472 did come from a realm of "fluidic space", where space was comprised of matter rather than vacuum, though their ships were able to operate in the vacuum of "our" space.
And the Sphere-Builders of ST: Enterprise were also converting "our" space to be compatible with their physiology, so the premise is not too out-in-left-field. Speculation is certainly fine, even wild speculation based on random and unconnected elements - that's how some of the best conspiracy theories are formed.
And that's really all I can say on this - other than Thanks for All the Rep everyone.
And maybe, sorry OP, but you've become the first person to make my blocklist, and you know why.
