The whole problem is the "company"
Ultimately, management does not care one little bit about the community that is slashdot. The only purpose that slashdot exists for them is to generate a profit.
If the company alienates it core users but gets twice the number of new people and make a profit, then that is what they want. They may actually think that way, and either way, they don't care at all about the core users. They only care about how to use the slashdot.org domain name to make a profit. What they are less likely to think is that after the core users go away, the site will slowly die. But we see this happen all the time.
It is the current mindset that all societal functions should be owned by companies and thus are not worth existing if they are not profitable. We know that this is false because many functions are filled by non-profits and government. Government is inefficient and non-profits lack funds. However, that does not mean that the knee-jerk reaction that everything should be privatized is correct.
In general, the current idea on companies is that the customers and users exist for the benefit of the company. That is the wrong way around, companies exist for the benefit of the people. If a company serves of no use to society and/or harms people or other things more than the benefit to society, it really shouldn't exist. The "company" is an artificial legal entity, it is not just sanctioned by the government, it is defined by government. The reason for the company is to allow society to benefit from a business that doesn't end with the lifetime of the proprietor. (Sorry, no citation, but I do have a business degree. However, does it not stand to reason alone?) Rules are added to be sure that companies do not harm society. These days, companies have run amok and some are damaging society. Companies are even controlling governments now.
That is a really sorry state of affairs for the world to be in, and it is the reason for what my username is.
Slashdot currently serves a very useful function for it's users and thus it is useful to society. However, with the current methods to value assets of a company, that means nothing. In general, there is no know solution to this conundrum.
However, given that slashdot is a dot org, why is slashdot not a non-profit entity supported entirely by it users? If it was a non-profit, then the management goals would truly be aligned with those of the users. Given who the slashdot user community is, the entire site could be run by the users.
Why not just get a new domain like slashdot.cc and recreate the functionality required?
