I've never heard anyone complain that copying a URL is too onerous.
I don't get what they're plan is. How does a company that is currently losing money plan to make more and be a sustainable enterprise by adding features that only increase their costs? Video uses a lot of bandwidth. Especially compared everything they've done so far (i.e. all text).
They had a good thing going with the mooching off free hosting on YouTube and Imgur. Why kill that? All I see them gaining are a bit more details on how many times someone played a video. And you could probably do that with some custom JS wrapping the YouTube player (guessing here ... not sure how that works in practice).
