OK, glass of cold water everybody and a deep breath.
This discussion , as I understand it, did not start about who has final authority ( the PIC has we agree ) but about following or not an ATC instruction to stop or cancelling a Take off clearance . These are 2 different things.
Stone cold : When I work(ed) I did not look at Wikepedia but at my Ops Manual , which is based on the AIP of the FIR I operate(d)
Just checked, still there , google the AIP GERMANY , ENR 1.1-16. pilots guidance.
Chesty Morgan : Do not shoot the messenger I did not write this.
But in my 35 years experience as a controller , in a quite busy piece of airspace, I never , ever encountered anyone refusing to follow my instructions. Nor I have heard of one . So we are here debating about the sex of the angels ( French expression ). This does not happen in reality and neither it did in this case ( the SQ stopped as instructed )
Stone cold again : If you want to discuss ueberlingen read the official BFU report , not ASN...it will save you embarrassing yourself.
