This is a gross mischaracterization of what's happening. People want to build interactive pages and products with neat little shiny user-friendly doodads. JavaScript provides that ability. SSR allows you to write JavaScript that will be rendered before the user ever sees it so all that effort that went into making browsers really good at rendering HTML can work for your interactive applialcation too. I have to assume anyone who doesn't understand the goals or says some nonsense about it being about "advertisers" has spent little to no time in this space.
