Perhaps we could (all!) cut back on the drama here. Disagreements between mappers are frequent; nobody owns a place and nobody does it right all the time. Barging into an area someone else is spending a lot of care on and establishing one's own (micro)mapping style can lead to conflict; being territorial about the area one has spent a lot of care on can also lead to conflict. An area where nobody reviews new changesets can quickly deteriorate; an area where someone over-reviews everything can stagnate.

About 8,000 people edit OpenStreetMap every day, there's bound to be different viewpoints and we need to find ways that work for everyone. If you feel offended by something, take a deep breath, maybe do something else for a day, and if you still find something is wrong, raise it on a community forum so that others who are not emotionally involved can give you a hint.

If you've done OSM for 15 years and liked it, don't throw your toys out of the pram just because of a single conflict; weigh that against the positive feelings that contributing to this fantastic team (!!!) effort has given you over the years - and allow others to have a little of that too.
