it is $13.99 / month in the US now. $150/year is a lot of money - for a product you can choose not to pay and still mostly use.
(Assumptions: I watch 10 hours of YouTube videos per week, YouTube shows 30 seconds of ads per 10 minutes of video)
$13.99/mo is at streamer levels who spend millions on production on top of infrastructure cost and allow you to share (within same household).
$23/mo for family is just plain robbery.
