#2Excellent! Dark matter is a kludge, the modern "ether". It's clear that we are missing something - maybe this is it...

Phlogiston, C-field... the list of such "placeholders" is pretty long.

Also discusses Professor Oppenheim's paper.

Dark matter is an observation, that several independent phenomena give the same estimation of baryonic matter mass, which is roughly 5 times higher than estimations of visible matter.
Does the article explain or even enumerate all of them?
At a glance, it is just a ‘quantum’ justification for MOND, which only deals with galaxy rotation curves.

Yeah we should stop calling it dark matter and call it “missing matter” or “the unexplained matter issue” or something that is more obviously a placeholder.

Worth noting the author disagrees with the theory and states as much a few times in the article.

Dark matter is a proposed explanation for an observation, that's all. All these other theories (MOND, etc) are also kludges. Nobody has a satisfactory explanation for galaxy rotation speeds, yet.

Why should the academic community care about your opinion? Dark is a very accurate term

If it is matter at all, then we do know something about it, that it is "dark" (does not interact with electromagnetism).
The alternative is that it isn't matter at all, and that some other explanation is required for galactic rotation curves, the Bullet Galaxy, observed gravitational lensing, and the configuration of the cosmic microwave background.
It's nice that one theory currently does all of that. That doesn't guarantee that it's right, but it means it's more than just "we have a guess about one thing".
