I don't see any correlation between the £500k continuation cars and fibreglass replicas. They're different products for different customers.
There are plenty of other Jaguar replica manufacturers that are still in business. Why haven't Jaguar closed them down too ?
I'm sure there's more to this than is revealed in the press release. Roger did have a stroke some time ago and while he was recovering, the running of the company perhaps wasn't as it should have been.
One issue that's been discussed on the internet, in relation to this, is the use of donor identities on replica cars. There are numerous replicas (not only Suffolk) that are registered as XJ6 saloons, for example. Whether this has any direct bearing on the Suffolk saga remains speculation at the moment.
