What? Apart from iTunes and Amazon, everyone offers FLAC. It kinda sucks that the two biggest digital music retailers don't offer lossless music -- which doesn't seem to be a big deal to most of the people who use both services -- but if you're buying music that isn't offered from a major label, it's pretty easy to find a service (or even the label itself) that will offer the album to you in FLAC.
Who is offering FLAC? I'm mostly just aware of iTunes and Amazon, since they're the biggest like you said. I know some independent/small people are but there's not a lot of coverage there.
The rest holds, though! No one I'm aware of is selling accurate dumps of games and saying "play it on whatever platform you want." That's how game preservation should be handled.
