Even the history of this is fascinating. This is the "[https://www.cntraveler.com/story/moses-bridge-the-netherlands-bridge-under-troubled-water](Moses Bridge)", and it's a renovated part of the old dyke system that was used to prevent attacking armies from getting in - because the dykes and levee's had blocked the sea so effectively, they realised they could stop attackers by... flooding them out. Literally.
When it came to renovate this area, they wanted to provide access without denigrating the fact it was an old defensive structure, hence this unique sea-level bridge.
I appreciate your point, however - if you wish for this series of communities to succeed, it needs to be welcoming to newcomers. And one of the ways of doing that is allowing for a continuation of conversations that were on the source communities - including, "Oh, we're getting out", "Why it's so bad", "Where do we go to", "How do we make the new community look/feel like I'm used to", etc. etc.
I'm happy to see this because it means that a corrupt and non-people-focussed environment is losing members. Like anything, it will pass, but please don't push people away by making them feel unwelcome.
