I agree with you. They are hiding date, promoting AI generated video craps, and tricking us to click on shitty advertisments etc. I'm not even using official YT app instead I use a FOSS client now that cuts the crap of shorts, ads, and personalised experience. And for websites yes! Whenever I see a content on web and it isn't clear when it was created I just leave it or might read it if the content is based on very general topics.
