Tesla/Musk.
Back in 2014 Tesla and Ecotricity had an agreement to upgrade Ecotricity's charging network to be compatible with Tesla's superchargers. Tesla whined that it wasn't being rolled out fast enough. Ecotricity wasn't a very big company and was basically working for free, so asked Tesla to actually support the roll out if they needed it faster. Musk went mental has been trying to destroy the company ever since. The 2014 Tesla patent release was never about collaboration or saving the planet, he just hoped somebody, somewhere would use it to undermine Ecotricity.
I have a friend who went on holiday in Amsterdam. Got a flight back home. When he got in the taxi from the airport, the driver asks if he smokes weed. "Yeah a bit. Why?" "Cause you've got a bud stuck to your hat". Dude managed to go through customs with weed on full display on his beanie and didn't get caught out.
