As Meta blocks mainstream news in Canada due to its abject refusal to pay for content the only news available on their platforms mostly comes from publishers that tend to have extreme bias in their reporting rather than the journalists that actively make an effort to confirm leads before publishing. That's absolutely going to have an effect on the quality of the material available to people that live inside of these bubbles. Not sure that's a good thing for the long term functioning of society. High quality news content requires money to pay journalists. There's no way around that fact.
