F-Droid changed the label to Non-Free Network Services because just linking from a POI to a booking site alone (without affiliate linking etc) isn’t the privacy nightmare fdroid wants it to be.
I could use OM my whole life without clicking links from POI and never is anything exchanged with Kayak or OM.
If one does a booking at Kayak then sure Kayak takes all kind of PII. OM wouldnt know btw.
Non free network label is assigned because OM app is dependent on OM providing mapdata. And one cant change that. Its like OSMand can provide for OM or vice versa.
