"Watermelon" (for lack of better term) OERs?

My background is in environmental studies, and one of the terms frequently used (usually with regards to companies/products) is “watermelon”- green on the outside/superficially beneficial, but red on the inside. I’m naturally skeptical, and I’m wondering if there is a general list kept of known vendors/resources that are marketed as “open” or “low-cost” but actually reveal themselves to be more predatory?

That’s an interested and new to me metaphor!

I find it referred to as watermelon status or watermelon reporting

You might find more about this under the concept of openwashing – see https://openwashing.org/ which comes from the practice in environmental science you might know of as greenwashing One of the early posts on this was in 2009 by Michelle Thorne

No list found, but it looks like there was an attempt to collect tweets for offenders under a hashtag of OpenwashingNominee (but that’s empty) - there are more tweets under the general #openwashing hashtag

I am loving though the watermelon metaphor, that works so well.
