OSM might also feel more pressure to standardize things like tags for features, which would resolve a considerable problem in using OSM data. Both tag names and value formats vary from region to region, and that's probably why almost any proprietary maps software is more useful than OSM apps. Having personally had to use OSM data, writing heuristics to parse tag names and values is a lot of work.
As for criticism of Overture on OSM community forums, there seems to be a lot of vague gesturing at "big tech bad, OSM community good." A more constructive place to look for what Overture means for OSM is the OSM Foundation's blog/press statement - https://blog.openstreetmap.org/2022/12/22/views-from-the-ope.... Which, to my mind, reads as saying that OSM data is free to use for corporations, but OSM hopes that Overture improvements flow upstream.
If my tone seems a bit negative, it's because I'm a bit tired of the negative reaction open source communities tend to have when being challenged or offered a collaboration opportunity with big tech. I feel like the approach Blender takes with big tech (like NVIDIA) is much, much more productive.
