I wrote a post on my blog about my concerns for the project, and some ideas for improvement:

It was not met well. I was (and still sadly am) subject to personal attacks by certain members of the OpenStreetMap community.
I don't know much about Overture Map, but standardization of tags, and a more sophisticated data model would both be very welcome, and make a map built on this data easier to work with.
More to the point, it's never been the technical issues that have held OSM back. Instead, as my post tried to point out- the technical issues stemmed from issues with leadership.
The post here mentions issues with the OSMF. At the time I wrote my post- the OSMF was largely symbolic, and certain community members simply held the key to certain aspects of the project- everything from servers, to software used, and more.
It was a huge mess, and I'm cautiously optimistic in seeing something new come around.
