Sometimes edits are easier on the contentious pages. There are more people looking at those pages and so democracy can prevail over time. But edit an almost unknown page and someone may jump out of the woodwork. There are editors of small pages, especially original page creators, who jealously guard their tiny mountains.

Some communities have a latest substantial author owns the page policy, along with a major edits only policy, which tends to work better for math and CS where there’s a lot of people who want to make micro corrections.

Technical communities also value professional credentials and prestige as a blockbuster, so it may be helpful to reveal your professional achievements.

Wikipedia generally does not (if anything it would probably count against you as most people who bring that sort of thing up are lying about them anyways).

Sometimes people are unfairly reverted, but often people are reverted for good reason and have problems accepting that their edit simply was not a positive change to the page.

I'll second this (over a decade of low to moderate activity). I've seen contention of course, discussions do occasionally get heated, but territorialism doesn't appear anywhere near as frequently as I've seen in similar projects, like OSM.
