I have reverted this changeset, see: https://www.openstreetmap.org/node/12702212278

OpenStreetMap is pretty strict in what should go into a name= tag. Not everything written on an object is a name. The text on an ad poster is definitely NOT a name.

And as other local community members have already mentioned, we do not normally tag changing ads at all (not even in a more suitable tag such as board:title= or inscription=). They change way too frequently for that (so they are useless as landmarks for orientation, because by the time one gets there, the text is likely to already have changed), and we also do not want OpenStreetMap to become an advertising platform by reproducing advertisements.
