Lol myetherwallet.com (MEW) is the most trusted ETH wallet ever i used. Well even my friends they are all using MEW wallet because of the nice and we our all the one that have are Private Keys.
Yes myetherwallet.com is not a scam and a very trusted eth wallet, maybe this person is talking about that other phishing site that looks exactly the same so it would be better to bookmark the correct site to be safe and lets all be vigilant and careful since there are plenty of phishing site's these days.
