ELI5: What happened to Shia LaBeouf?

I've been seeing so many articles about him and the fact that he wore a bag over his head which read "I AM NOT FAMOUS ANYMORE" to something important.  His latest tweets also say that.
gpt
Basically he 'wrote' a film for Cannes Film Festival last year which turned out to be plagiarised mostly from a graphic novel writer, who was not credited. He was found out, and savaged by the media. His apology tweets (really, thats insincerity in a nutshell) were also strikingly similar to text already about on the net. This was also picked up on by the media. As a result, he announced (by twitter, again) he was 'retiring from public life' - whatever that means.
*Apparently* it means wearing a paper bag on your head to red carpet events, saying 'I am not famous anymore' and walking out of your own film's press conference after making a ~~pretentious~~ enigmatic reference to a fellow disgraced celebrity.
