There are still people who believe that today. It all depends on what you want to believe. People believe that Russia was forced into this, people believe that Ukranians secretly long to be liberated and saved. People will believe the most crazy stuff.
Zelenskyy himself was telling people to calm down with the invasion rhetoric, indicating that there is no evidence of an imminent invasion, and that the rhetoric is counter productive.

I hadn’t heard of that before.
