No problem

Based on aircraft fence designs, these curved strakes look like fences to help turn the airflow around the outward curving side walls without having it separate.

that´s my take on it ...the strakes help fill the whole volume of the diffuser .It´s a trade off -you add surface drag by introducing further aero surfaces but you also keep the air attached in areas with lower speeds and too acute angles ..
the strakes have sharp edges for a reason as well as VGs in areas of need ...

About the material which the diffuser is built of .. Is there a reason about squares of light gray and dark gray, like in a chess game? I don't understand

They use Textreme from Oxeon, a Swedish manufactor of special carbon fibre. They deliver to all teams. Google and learn about the benefits.

the weave is clalled spread tow it is just short of being two layers of unidirectional fibres laid up at 90° it´s quick to lay up and it has a good drapeability .Convenient .
