I started editing a page which was a list of scientific software for a specific application. Something really useful if you ask me, as it’s difficult to find a complete list of those, you’d mostly be waiting for someone to publish a review on the topic. After a while someone came around and decided a bunch of items in that list were not relevant, he did in fact delete the most widely used software and left some very old and discontinued ones. I explained that was a mistake and that it would render the page useless, but apparently it is not considered useful to have a list of things if the individual elements of that list are not considered worth having a page, and those were not considered worth having a page because nobody had decided to make one page.

I turned to wikidata and found a very good source of data and a much friendlier community.
