Unfortunately in my case, I'd had to abandon that email a while back, so I didn't really have any options when a harddrive failure took a chunk out of my game collection, and I couldn't find a way to actually change the email attached to my BMT purchases. It's mostly water under the bridge now, since I've been able to rebuy every game I lost in one manner or another. But I have taken to preferring Itch.io first and Steam second, as in both cases keeping my accounts just came down to changing the email attached to the account before I had to abandon it. DRM-free for me is a nice feature to have, as I do spend a lot of time gaming in places without internet access, but as far as DRM goes, Steam's is both reasonably unintrusive thanks to offline mode, and reasonably circumventable if for any reason I had to remain offline too long for that to work. I mostly just asked because just because I can work around steam's problems, doesn't mean I wouldn't prefer to not have to...although, pushing a drm-free version to steam would also be pretty cool, whether it was instead of or alongside an itch.io release.
