The most annoying thing about Gemini is that it can't stop suggesting youtube videos. Even when you ask it to stop doing that, multiple times in the same conversation, it will just keep doing it.
And I say this because, I added about 50 prompts in the settings to prevent video recommendations and to remove any links to videos. but I still get text saying "the linked video explains this more" even though there is no linked video.
This is not a bad way to monetise the free tier. Non of the other token providers found any way to monetise the free tier but Gemini is doing it on almost every prompt.
