This is one that sounds worse than it is, Dyson offered to make ventilators when everyone was scrabbling around for the things and thinking that we'd need 1000's more of them, he asked that British people based in Singapore (lower personal tax, natch) would not have their non-dom status affected if they came over to help with the ventilator thing. Of course the whole non-dom thing is shady as fuck to start with and practiced by utter scumbags, but if you have that system in place and you're the kind of scummer who used it, then it is reasonable to ask that your status is not affected if you come to the UK to help in a national emergency. On the scale of other shit that is going on with this kleptocratic government, this is nothing. Still need Dyson's smug, grinning head on a spike though.
