Mr. Rossmann owns an electronic repair shop that specialized in repairing Apple laptops. Apple sued him because he wasn't an authorized repair facility; they lost. Apple sued him to try and stop him changing laptop batteries because Apple had designed the laptop so the battery could not be replaced; again they lost. Apple sued him for importing unapproved replacement parts; again they lost.
Mr. Rossmann became involved in the fast growing community pushing for the right to repair all products. This led in part to the mandate that all USB connectors be standardized; no more Apple releasing a new product but with a propriety connector forcing to you buy new earphones etc.
Rossmann started the FULU foundation which offers a cash reward to anyone who can hack appliances that would shut down if you did'nt buy subscriptions; for example.
