It violates copyright, yes.
If you're interested in contributing opening hours data, but learning OSM's quirks sounds too hard, try https://streetcomplete.app (for Android and soon maybe iOS).

As an avid OpenStreetMapper I’m sorry you’ve been shouted at for something that is „not recommended“, but not really a big issue. This should not happen in our community! At most someone should have told you to try to avoid large bounding boxes as it is much easier to review geographically small changesets.
Sometimes large ones happen, especially if StreetComplete is set up this way, as matkoniecz mentions in another comment.
have you enabled manual uploading (that needs to be done in settings and warns about need for triggering regular uploads)?
or have you edited just before and after air travel, and enabled plane mode before changes had chance to upload?
Of course, if Google decided to fight it as a copyright issue you’d still probably be screwed, even if you were in the right.
