So they are handing data to HMRC . I think this could have media legs 

17/18 and 18/19 for now.  I imagine HMRC will be seeing a lot of amended tax returns coming in for future tax years....

If you mean in the sense of bad publicity for prominent exposed tax cheats, sure.

If you mean that anyone will care than Airbnb have given records to HMRC, lol no.
