Hong Kong - Anyone is using OSM in HK?

As written on the Subject…

I’ve done plenty of hiking in HK using OSM in my phone (Locus Map app). Hong Kong is brilliantly mapped, especially the trails which are of interest to me, so obviously people are also using OSM in the sense of adding the trails they’ve walked, not to mention all the usual city detail.

The OSM map of Hong Kong, especially in topographic form, is a thing of beauty.

Why do you ask?

Because my tech company is using OSM instead of Google.

Seems not many people or company are using this in HK.

Do you know any company?
