It's my internet connection I want to share, so I naturally expect to set its interface, the upstream one, to 'share with other computers'; the upstream connection is what I'm sharing, and is therefore be the object in the sentence "Share my internet connection with other computers". Well, it'll be nice psychology study which will show just why Joe Average gets the facts backward, but this logic is obviously quite strange. Let's forget about network, routing, packets, etc. Suppose my neighbour lost electrical power and I, ever the helpful guy, want to share my grid power connection with him (electrical grid, not Internet). Now, I have two choice: Somehow when electrical grid is concerned everyone automatically assumes solution #2 is right, but for Internet they want go and try to change WAN#1 (their WAN connection)? WHY? What's so special about Internet? P.S. This phenomenon is quite obviously present because Microsoft tries to “help” here. It ALSO makes no sense to change WAN configuration when you share it even in Windows, but hey, if people en masse want to do this strange thing then this is how it should be done. As a result when you share network connection you must “alter” WAN connection, but this is illusion. When you try to “share” WAN connection in Windows WAN connection is not changed at all. Instead Windows goes and silently changes LAN connection behind your back. The end result is essentially the same as with Linux, but with a twist: in simple cases everything “just works”, but in complex cases you must imagine these behind the scenes changes and do complex dance (Ok, I need to change this network in this and that way, but this is impossible to do so I need to create fictive temporary network and change THIS, then I can delete it because it's unneeded and I can fix THAT and but this well mean that networks will be disconnected but this can be fixed later…) I hate that.

#1. the entire concept of LAN vs. WAN only propagates this confusion
#2. The Linux way of electricity networking does exist in your 2nd electrical example, its called a Widow-maker or other similarly ominous names. (for good reason)

(for good reason) s/Linux/Windows/ Widow-maker is used to attach to the upstream, to “WAN” power grid (this is what you “naturally expect” for some reason). This is Windows way. In Linux you share your wall outlets (you local in-house “LAN” electric network) instead. the entire concept of LAN vs. WAN only propagates this confusion Why? WAN == WIDE area network (think city-level or even wider electrical network), LAN == LOCAL area network (think you own tiny in-house network with dozen or two plugs and few appliances). If you want to share electricity with someone you most definitely will do it using your local network (unless you have some serious reasons to use thing which is called Widow-maker or other similarly ominous names).
