100%. Looks like they're using pangram (hope they're getting that for free...) which also flags stuff like Grammarly. That one's an interesting gray zone to me that I've not thought off before. LLMs whales doing the heavy lifting is one thing, but small edit tools like grammarly that "improve" your phrasing are likely a massive algea like contributor to what is out there too.
Why for free? Wikimedia is very well funded, and I'm sure that Pangram could use a leg up...
I've felt that like tools like Grammarly are harmful for native speakers. I get if it's not your first language you need extra help, but if you are a native speaker these tools only serve to homogenize your way of speaking.
Having a program constantly suggest "better" ways of phrasing things is stripping your personality from your language. Maybe this is needed if you are writing corporate PR pieces, but you should avoid it for anything else.
