The responsible and effective implementation of privacy here would be to
configure your webbrowser to prevent websites to load external data
like images. This is course fairly theoretical since a lot of websites
would become unusable.
If you turn off referrer transmission w.r.t. tiles the only effect this
has is it prevents the tile provider from knowing what website you were
requesting the tiles from. It does not prevent the tile provider or
the website operator from learning about your map browsing activity.
In case of non-free tile providers by the way use of API keys and
tokens means the website is known to the tile provider even without a
referrer. So you'd just punish the free services by withholding them
information others get despite these measures.
