It seems utterly, utterly insane to me that the vendor of a currency wallet software would leave the .com of their product's name unregistered. Using the real Electrum at home but second-guessing that now.
Apparently the previous owner of the domain was trying to sell it for "the price of a house", not something an open-source project can typically afford.
I'm not a python guy, but from the screenshots I don't see where it is requesting something other than the version, I don't see where it appends the seed keys or anything on the check version request, but I don't use this or any wallet to care enough to verify.
