This is such an odd title to an article. Is the fallacy ever a good thing? The fallacy itself is a concept - so not really good or bad. Using it as a logical premise in an argument is recognized to be problematic.
Are we actually asking: is ever good to keep doing something you yourself hate only because you yourself already spent money on it? The answer seems clearly to be no.
Might we easily make it more clear that the poster or the server owns them outright?
Hypothetically, a corporation federates and wants to monetize my posts. Can they do this? I’m not personally fixated on ownership (which could easily be viewed as my systemic privilege), but the pathway out of this type of thought in general doesn’t seem to be yielding all power to already powerful growth-based corporations. I didn’t create the current systems, but I do acknowledge their existence.
