True, but it does make it much easier to make the case that they registered the domain a year ago with the intent of launching that brand and have been working on the idea ever since, while we know that Twitvid.io just spent a few days throwing this together a couple weeks ago. Hardly an airtight case for trademark protection.

I'm not saying what they did is right, as it clearly isn't, but I agree with axod; Twitvid.io should just change their name and move on. They're going to fight a losing battle otherwise.
