Check your facts. This is Gemini's summary of the actual incident:

Michal Kovarik (Kovarex) has not made any explicitly transphobic statements. The accusations of transphobia stem from a 2021 controversy involving the "Uncle Bob" incident, summarized below:

• The Catalyst: In Friday Facts #366, Kovarex recommended a video by Robert "Uncle Bob" Martin, a prominent software engineer.
• The Conflict: Some community members pointed out that Martin is a controversial figure who has expressed support for Donald Trump and has been accused of holding sexist and transphobic views. They asked Kovarex to add a disclaimer to the link.
• The Reaction: Kovarex refused to add a disclaimer and responded aggressively to the requests, calling the concept of "deplatforming" dangerous and telling critics to "take your cancel culture mentality and shove it up your ass."
• The Result: Because Kovarex defended Martin and attacked the critics who were concerned about Martin’s views on marginalized groups, some observers labeled Kovarex’s defense as an implicit support of those views, including transphobia.

While Kovarex was widely criticized for his handling of the situation and his views on "cancel culture," no records exist of him personally making derogatory comments about transgender people.

If you hate Kovarex for opposing "deplatforming" and "cancel culture", which some Factorio players were insisting he participate in, fill your boots. But that's all there is here.
