“[…] by the government”
What government? I guess, since this is BBC, that it’s the UK government, which means diddly squat for the rest of the world.
I believe it is in Denmark as well. However, online reviews are only ever of use when it’s not on the company’s own web pages. If you control the platform and get a bad review, you’d just delete it. There’s many 3rd party review platforms, but most have the same problem, that they are paid by the company’s and therefore the companies control the platform and can have bad reviews deleted. There’s been many cases of this on the Danish based Trustpilot.
