Thin on the right so far

Only 4 of the 20 outlets with a published leaning rating that ran this story are rated right.

This story is still being watched, so it is a count and not yet a finding. Coverage keeps arriving for hours after an event, and a side that has published nothing this morning may publish by tonight. If it is still true when we stop checking, we will say so plainly.

The campaign of Brazilian President Luiz Inácio Lula da Silva filed a complaint against Meta, the parent company of Facebook, Instagram, and WhatsApp, with Brazil's electoral court. The complaint, dated Thursday, alleges that Meta employed biased algorithms and artificial intelligence restrictions to favour opposition candidate Flávio Bolsonaro in the lead-up to the country's presidential runoff election on 25 October.

According to the legal filing, Lula's campaign stated that Meta subjected their materials and organic posts to "unjustified reductions in reach." The filing also claims that Meta has not adhered to a plan previously submitted to the electoral court to address these issues. Lula's campaign asserts that accounts and advertisements associated with Flávio Bolsonaro have received artificially amplified visibility, with engagement metrics comparable to those of global celebrities. In the first round of voting on 4 October, Flávio Bolsonaro secured 47% of the vote, while Lula received 45%.

The complaint further alleges a disparity in Meta's AI tools, noting that users were unable to generate campaign images for President Lula via WhatsApp's "Meta AI" feature, but could do so to promote content supporting Flávio Bolsonaro. Lawyers for Lula's campaign stated that Meta's content delivery is selectively restrictive towards the incumbent and favourable to Bolsonaro. They are seeking an order for Meta to cease content restrictions and to increase Lula's reach to compensate for perceived harm.

Meta has responded to the electoral court, rejecting the accusations of bias towards Bolsonaro. The company acknowledged experiencing technical glitches that impacted accounts beyond Brazil. Meta stated that it operates in full compliance with Brazil's electoral regulations and is committed to providing equal platform access for all political parties.

Disagreement on AI image generation

The Lula campaign claims users could not generate campaign images for President Lula using Meta's AI tools, but could do so for Flávio Bolsonaro. Meta has not directly addressed this specific claim in its response to the electoral court, instead issuing a general rejection of bias accusations and citing technical glitches.

What the coverage left out

None of the left-rated or centre-rated reports mention the specific date of the runoff election, only that it is scheduled for 25 October. The reports also do not detail the specific nature of the "technical glitches" Meta cited in its defence, beyond stating they affected accounts beyond Brazil.

Still developing. We have re-checked which outlets are covering this 3 times, most recently on 17 Oct 2026, 00:30, and will add the sides that appear.

Is the coverage of Lula campaign sues Meta over alleged election bias biased?
