I could see that, for sure. I don't enjoy online gaming at all so don't have much experience, but i'd guess the fact you are already looking at a flat screen rather than around a table means the memes popping up in the chat window aren't taking your attention away from something else like they would in person since sending a Dramatic Groundhog GIF achieves the same result as typing out "Holy Moly, the ghost was really the caretaker in disguise this whole time!"Under COVID, most of my games have moved to Roll20. We use Discord for voice, but there's also the text chat. And it's interesting to me how posting funny junk where everyone can see it seems to work better than doing the same in a face-to-face game with a personal device.
In a weird way, commenting on the game with relevant memes seems to work in that kind of environment, showing that the player is interested and engaged with the action. I guess maybe it has something to do with being in a separate digital space than the Roll20 tabletop. It easier to partition "funny asides" and "the actual game" that way.
