Donoreo threads were almost always near the top of search results
Keep in mind that on DSLR a fair amount of popular posting (by volume) took place in closed forums (Pub, etc) that was not accessible to search engines to index.
Not to rehash the “get rid of the Open Forum” again, but maybe the Open forum (and maybe a separate dedicated “In the News” forum) could be blocked off from search engines (via robots.txt or similar) if quoted material there is mucking up search results. Leave the truly Tech areas open for search engine indexing.
Another compromise would be allowing the quoting of a small amount of text, just enough to convey a point or provide a summary. 1-2 sentence max.
FWIW, I did not see any issue before this with the exception of some posters posting those excessive walls of text.
