That doesn't make any sense. Hits to 25 KB Wordpress blogs are trivial for ISPs to serve, nor is there usually any practical or economical way to bill the owners for serving them. It would cost many orders of magnitude more to create a blacklist and/or to track down and attempt to collect payment from the owners than just to continue serving them as before. It's the 25 GB 4K 6-hour Netflix binge-watching sessions they'd want to be subject to throttling/charges.

Whether that's a good thing for the consumer is debatable — it probably isn't — but there's no reason for fearmongering. Many countries, including the US for most of the past several decades, have no or have not had "strong net-neutrality laws" without "migrat[ing] to the internet being limited to the top 100 sites (curated by [ISPs])."
