Can someone explain why this only affects the player that joined?

game.Players.PlayerAdded:Connect(function(plr)
	game.Lighting.Blur.Enabled = true
end)

This makes blur enabled when a player joins. What I don't get is why it only makes the player that joined have blur, since it isn't a local script. Can someone explain why it acts like a local script?

Things, why it may be acting like a local script, are:

• using a game.Lighting.Blur without localizing them
• having a function(plr)

If this script helps you feel free to accept it!

How about this script:

local blur = game.Lighting.Blur

game.Players.ChildAdded:connect(function()
	blur.Enabled = true
end)
