I don't see any evidence that Google applied a misinformation policy here. It could be that they simply don't want to pay for the bandwidth to serve video without any ads in it. It is a big file and a lot of people want it. That can get super expensive.
I don't know how big this file is, but let's say it's a 4GB DVD image. That ties up 1Gbps for 32 seconds, which means that with a 1Gbps link to your server, you can serve it to less than 3000 users a day. Even if you're getting budget residential ISP prices for your transfer, you're talking 1 cent per 10 copies of the video. At AWS prices, you're talking 36 cents for every copy of the video downloaded.
This sort of thing is why you either peer with an ISP at 10Gbps or more, charge money for file hosting, or use a p2p file sharing application.
Until I see some evidence that this is misinformation censorship (for example, Google removing a private file with a transcript of the video), I'm going to assume this is just limiting the impact on other users from a free user with a popular huge file. As HN always says, if you're not paying for something, you're not the customer.
