The Critical Drinker - a question

I was looking through his channel, and pulled up one of his older videos (I had just watched his June one on Ghostbusters 2016) and saw a video on Ghostbusters 2016 from 2 years ago on the feed. Considering in his June 2020 video he mentioned he was just then watching the movie, I was curious.

The video certainly implied he had scene the movie specifically to critique it, but a few things stood out:
1. His style of commentary was different. Still entertaining, but way less of his own humor.
2. His voice was very different. Still Scottish, but a bit higher pitched.

I was scrolling through and found where it seemed that everything changed, and honestly I cannot find anywhere that someone mentions that it's a different person, but the last video with the higher pitched voice was about the Captain Marvel RT reviews:

Then the next one has the voice much closer to what we're used to and the humor we know, also about Captain Marvel (with sarcastic title to boot):

Anyone else know if the channel was sold or something? It's really striking listening to the older videos and comparing them to the newer ones, with humor and voice change - or is this a funny, drunk version of Ronald McDonald with a different person behind the makeup?
