Re: objections from Anders Povlsen ... invested a substantial sum in another space port
his objections (well, the objections of his company Wildland Ltd) are about the lack of provision of facilities for spectators (and the impact on the area), and poor demarcation of any exclusion zone around the launch site. No mention is made of any commercial conflict with his Shetland launch site. This may have been left out of the BBC's report.
Apparently the Povlsens are one of Scotland's largest landowners, having bought up several estates across the country.
