based on the dozens of sketches and process displayed in their shot, it feels purely coincidental.

It's not a unique shape or solution so it's unsurprising that someone else could come up with it.

The shapes are ultimately different, the ligature is missing and the angles are different, I genuinely don't think they copied your work.

As Aiste mentions, coincidence is not absolving in logo design. Due diligence to determine that a logo concept is unoccupied is a necessary part of the process. Lawsuits come up all the time when it is neglected (like F1 and Futuro).

That's why perceived difference is key.

Thanks, @Michael Cook for the share!
