True, but academic journals usually try to maintain some sort of acceptance ratio, and avoid accepting every submitted article. (If they do, they will have the reputation of not being selective, which will harm their rankings and will make people try submitting their work to more selective venues first.)

Of course, for commercial publishers, there is an incentive to publish more -- so there is tension between taking more articles (more revenue in APCs, more volume, easier to attract subscriptions, more perceived impact for extensive properties like h-index) and being more selective (more prestige).

So worse reviews probably doesn't mean more papers accepted but a more random selection of accepted articles.

Assuming that articles have some intrinsic "quality" that most researchers would agree on, and that good reviews are better correlated to this quality than bad reviews, one would expect that getting worse reviews would make the journal selection process (even) more noisy. This can harm the prestige of commercial journals (if they start rejecting articles perceived as "good" and publish articles perceived as "bad").
