No, a link would link to the YouTube channel so it would be good as well as the embed.

The creator doesn't get views unless someone clicks to play their video. Most people won't click to play the video.

Also this site makes no attempt to check if a video can be embedded before displaying the text.

There's a link in the embed itself too - what is your complaint?

They give credit to the creator - is your complaint that they shouldn't be allowed to summarize a video in text format? Like every blog or news that ever embeds a video does?

A small link buried in an embed widget which doesn’t even appear on every video is not sufficient credit.

A YouTube video has a description field, plus a title and the channel name. All of these should be shown at the top of the page, plus video creators should be required to opt-in to this service.
