The company did not go out of business, there are identical rides elsewhere and parts are available online. As far as I can see, the company filed for bankruptcy in France but didn’t go under.
This is what I mean, already 2 people have given 2 different answers. So the reality iis we don’t know exactly why they decided to close it. The timing of when the ride closed suggests the accident in the U.K. had a bearing on things. But the decision to permanently close it could well have had several factors, including safety, maintenance, cost, or other plans.
