I imagine what they can't say is that your feed is otherwise too empty. Whether you want that or not, that doesn't suit them at all. Newspapers back in the day would only run as many pages as they had ads to support. If they didn't have the ads, pieces already written and ready to go wouldn't be included. Unless you follow a long list of active people or semi-professional content creators, you're not going to see enough ads.
Now, presumably you hate this, and I certainly hate this, but without doing things their way, we're unwanted. They want the consumers and they want those that can be convinced to follow suggestions and join new groups.
Once upon a time, the technically literate would leave Altavista and join Google to start a migration, but Facebook buys the Instagrams and slowly twists them the same way to suit them. It's miserable enshittification.
