Love the idea, but the execution can be better. The photos show empty billboard frames, remnants of old ads against walls, etc., making things look dilapidated but not in an Anthens-ancient-ruin kind of way.
As the city adapted to the new rules, the frames were torn down, you could see the architecture behind them (sometimes veritable architectural treasures worth of preservation), and murals covered lots of the empty space in monumental art installations. Where the space is empty, you sometimes see art (and political protests) being projected on the walls.
Yes, the place would look objectively tidier without them. But, given the context of what they used to be, I would enjoy the daily reminder that there used to be ads and now they're gone
