Basically the same thing I replied to this same post shared on privacy@lemmy.ml. This 2.5 years old video proves nothing, I don’t trust Facebook nor Meta, but this is a poor quality post.
I love Organic Maps, it is clean, simple, and works for 95% of my needs. The rest of the times I resort to OsmAnd, which is heavier and more complicated but has many more options.
The house number search can be tricky with OpenStreetMap based apps, unfortunatey, but still better than using Google, in my opinion.
I used Magic Earth in the past, but it has some wrong information in my city (an important road is marked as closed and it calculates long detours) which is not coming from OpenStreetMap, so I personally don’t trust it.
I know about Obtainium, thanks, but I prefer to avoid having several different sources for apps. Besides, F-Droid builds apps from source and checks for anti-features, so it’s a nice to have check that the app is not doing anything sketchy.
