Electrek is pretty biased politically so this article should be taken with a grain of salt. Half of Britain is probably pro Musk. Buried deep in the article are the details, which is basically that a left leaning activist political group ran a campaign to flood the regulator with comments opposed to Tesla virtual power plants. That’s it. So it’s not about “Brits” in general but just one group using its members to fake the appearance of mass opposition.
