Pretty sure the synthetic oil- running in story has been debunked as a myth.

Porsche, Mercedes and many others are using full synth from new. I think the worst thing you can do to a modern big bore engine during running in is babying it or lugging it around at low revs for the first 1,000 kms.

Yes on modern engines, not on older engines.

No - more like they don´t need to be run in, I didn´t say old engines couldn´t use synthetic. But for some engines its not recommended.

Who am I going to believe when it comes to starting up - the engine builders and parts manufacturers or statements from oil companies?
