As you can see in the subject line, yes, YouTube now has the Like and Dislike buttons visible to VoiceOver and how much views there are.
If you remember before, you had to ask for sighted assistance to help you hit the like or dislike button. There also use to be a blank spot where the Like and Dislike buttons would be, but they weren't visible to VoiceOver.
We now have the Like and Dislike buttons visible now, so keep using the YouTube app like you would regularly do and you can like videos by YOURSELF.
Please note that if you don't update to the latest YouTube app version, you should do it to get the buttons back.
