nice to highlight the issue.
but why not fixing it ?

part of the reason for that was described a decade ago by Andy Allan:

That was talking about imports, but "poor commercial mapping in the hope that the community will tidy it up" causes the same problem.

Commercial mappers may be paid not for quality, but for quantity, and the sheer number of individual mappers can overwhelm local mappers' attempts to check their edits.  See for example this list: https://wiki.openstreetmap.org/wiki/Grab#Grab_Data_Team . Some of the problems that that led to can be seen at https://forum.openstreetmap.org/viewtopic.php?id=64075 , also in that forum see https://forum.openstreetmap.org/viewtopic.php?id=67707 for comments relevant to the edits in Panama too.  "Having lots of paid mappers" doesn't necessarily mean "will ignore local suggestions" - I can think of one very large group (perhaps the largest) who have been very responsive.

This potential asymmetry was one of the things that lead to the Organised Editing Guidelines being created: https://wiki.osmfoundation.org/wiki/Organised_Editing_Guidelines , and the list at https://wiki.openstreetmap.org/wiki/Organised_Editing/Activities .  Some organisations have been very open and responsive about what they were trying to do - generally these are the entries in the "Activities" table with lots of information.  Some have been, how shall I put it, "less forthcoming" and had to be asked by the DWG to create an entry in that table at all.

Best Regards,

Andy (from the DWG)
