Define "better off". Companies like Meta and Google are enormous behemoths that make their money through advertising. One advantage of their size is that they have lower costs, but a greater advantage is that they have much larger market power: they can purchase competitors and demand higher rents for advertising space. Is society genuinely better off from this kind of concentrated market advantage? One might argue that there are different kinds of 'efficiency' at play here, and not all of them are in society's interest.
