Aren’t microplastics from car tires more common?
I thought so too, and maybe they are using a different metric in this article, but I couldn't tell you since their source URL is a deadline.......
I also remember Coke, Pepsi, and Nestle being claimed as the highest plastic polluters as well.
This article is quite likely fake news. The first paper cited only says they're the most common pollution on beaches.

The metric is also "count", not volume/mass, so not a very useful metric at all.
Presumably plastic pollution is a superset of microplastic pollution
