It could also be that they only have the capacity to have a certain number of coasters running at the same time. Say, four thrill coasters, four family coasters and a kiddie. If another coaster goes in, one must have to go out. Removing the most reviled one (honestly, why did they even buy a Volare in the first place, given their reputation?) makes the most sense, and with it being so new and all, it shouldn't be too difficult to find another gullible sucker buyer on the second-hand market. Very few coasters are ever scrapped in the UK, they tend to be dismantled and sold.
