While this sounds plausible, fortunately it doesn't seem to be the case. We're hearing is that it's both improving student outcomes and making coding more fun and exciting for students, so much so that they continue coding after their class. This came in recently from a CS teacher in Mexico City:

> I am a CS teacher at a public high school in Mexico City, and I am fortunate to use Repl.it since the past October. My remote classes have gone so good thanks to Repl.it, my students have been learning a lot by working with your platform. They have even given me a C language code made in Repl.it as a present on my birthday.

We're also working with researchers to conduct a small study to see if this can be borne out in outcomes data.
