Yep, watermarked memes (and watermarked most things in general) are a scourge on the internet. I stopped following a Youtube channel that's mostly playthrough's of old fighting games because he suddenly decided one day to add an annoying (and ugly) watermark to the corner of ALL of his videos including the old ones.
Luckily, I'd found a similar one who was actually better at playing the fighting games themselves. I switched to that dude instead.
