Just an update:
As of the first of September, 2023, it would appear that X has now successfully moved access to "X Pro" - what was once called TweetDeck 2.0(?) - behind the X Premium paywall. For my own curiosity, I just bought a month of premium to see if I could get to TweetDeck from within this web app by using the "Leave X Pro" button, similar to what is depicted in my guide video.
I was unsuccessful in doing so - none of the opt outs appear to be working. Instead of redirecting back to TweetDeck, they redirect back to twitter dot com.
