just clicked the link in the change notification today.
p. 10 re-read it for a long time in this form.
You MUST NOT use the Service to sell advertising, sponsorships, or promotions on a page on any site or app that contains only Service Content or where it is primary (for example, selling ads on a page where YouTube videos are the only content of value).
for clarification, you can look at the license for the iframe version of the YouTube player.
Those. it is possible to make a site like xn--b1afajepzqk.xn--d1acj3b , but ALREADY it is IMPOSSIBLE to place ads on it

Answer 2

Either let the author of the content upload it himself, or through embedded blocks from Instagram itself, for example.
The same Yandex on its air lures YouTubers with fatter monetization.
And in the search, videos are visible from other services only due to the fact that this is a search, and the content is shown through native players of third-party sites.
