It's interesting how the author of this piece uses "badverts" and "badvertisers" because it implies that there are "goodverts" and "goodvertisers" in the settings he's speaking of.
As the author, yes. Some parts of the city are innately commercial spaces, and commerce requires advertising. But let it stop at colourful shop signs (even neon is fine, in a shopping centre!), signwritten vans for trades and deliveries, or the circus' sign on the fence of the public park. The badverts are the billboards covering up entire buildings; the LED pedestals that block your way as you walk and distract drivers; and the incessant advertising for unethical investment companies on public transport.
