That’s really dumb. Especially since Bitcoin has increased the block size and will do it again in the future.

It's a clever idea/claim to make from a rhetorical stand point. Politically it sort of squeezes out the last bit of small block juice.
I don't think there is a precendent for his specific claim, as the up to now the main justification has been that larger blocks will centralize. It's an outright linguistic salvo (goal post shifting) and technical red line that favors the Blockstream mafia.
It's meme worthy, a short pithy idea toxics can rally behind if it gets confirmed by the usual suspects or otherwise amplified.
Pic related is why these are the last days of toxics by the way, why we are seeing oddities like this line of argument and whatever is going on with Saylorites. The project is straining under, artificial constraints, state pressure, demand for privacy, and the "failures" of LN.
