'Make sure you weren't forcefully unsubbed from someone you like!' loosely translates to 'please make sure you're not unsubscribed to me, I need to hold on to as many viewers as possible, even losing one could mean I don't have the ability to do this full time anymore. I don't care about anyone else, just don't leave me'
His whole 'I don't care about views, honestly,' attitude has always bothered me when it's blatantly clear that it's all he cares about because he never shuts up about it. It's good to see that his bitterness towards Youtubers far more successful than him hasn't left Phil either. You can just tell that it eats him up when he sees other accounts with these fancy different coloured subscribe buttons.
