I think someone used to run his social media accounts for him over the last couple of years. Something about the way things were phrased made me feel like it wasn’t really him. I run the social media for the company I work at and Polunin’s updates tended to have the same odd formality that I end up using when posting about events I wasn’t actually at! So I could be wrong but I think it seems like this is him taking back control over his accounts. It would explain why his English has gotten worse.
