I run UBO, SponsorBlock on FF. I have many t-shirts and hats from youtoobers. Someone was asking about my hat, I said it’s a youtube channel, then they asked about my shirt and I said it’s another youtube channel. I then thought of all the t-shirts I have in my drawer at home. I’d say well over half of them are youtube channel shirts. Made me think I am too deep down the youtube hole, but there is a ton of good content and I like supporting the ones I watch and enjoy. So merch is how I do it so I can be their advertisement. I may not even wear it much, but I’ll buy to support them and to tell others about their channel.
