That is twelve years from now. Even assuming they stick to that plan, which I feel is a naive assumption considering how often they've failed to meet EV plans previously, they can easily continue poisoning the EV waters today and for several years to come.
VW has made multi billion Euro (~20 billion until 2027) investments into EV, from a completely new vehicle platform to investing hundreds of millions into battery tech startups. There was even serious talk about buying a cobalt mine which was abandoned when battery tech got rid of cobalt.
Why would they do that if they want to sabotage it? It doesn't make any sense to that to throw it all away later on purpose.
