I never understood why the people behind Bitcoin Cash didn't "manually" lower the difficulty at the forking block. This would've been a strong incentive for miners to mine the fork and could've been good publicity. Instead most people didn't bother to mine the least profitable fork which had the same difficulty as the "main" chain. That resulted in a few chaotic days where almost no blocks were mined before the difficulty automatically and slowly adjusted.
