People with worse vision still have a higher chance to die due to poor vision related deaths, (for example not seeing a car coming) than people with perfect eyesight. Not everyone with bad eyesight wears glasses.
It does not. But it means they are trying to limit the damage caused by griefers, and moreso than just displaying a popup message with "please don't grief openstreetmaps" or something. Imagine how bad it would be if changes to openstreetmaps actually were immediately imported into the game...
Why does every article fail to mention that the ingame map only updates once every 3 years or so? And that this griefing is most likely done once per person, until they find out that the game isn't updated? (Because it's not sensational)
Nothng changed.
