Maybe but Vanced was undeniably easier to use and transition to if you were used to the official app. I knew totally tech illiterate people using the app specifically because there was 0 difference with the official app. Once they just got it installed by someone they knew everything just worked and it was easy to update. Very very different from newpipe, which barely even has support for basic features like subscriptions.
FYI it's a reference to something else. He's basically calling you a fed/gov shill. It's a reference to glow in the dark CIA agents that schizophrenic late programmer Terry Davis claimed were following him. So it turned into a meme, and now glowie means fed/3 letter agency/police and saying that something glows means it's shady. I dont know how he got that from your comment.
(A comment that "glows" would usually be something like: hey fellow members of radical political ideology, who is up for letting those politicians know what lead tastes like? Let's conspire to commit domestic terrorism!" )
