Joe Bloggs can go out an buy an ex military aircraft and fly it on a PPL with little or no restriction.
Despite the high value of these airframes and their display capabilites there appears in recent accidents to be a lack of control risk and experience.
The above may or may not be relevant to the accident that is the subject of this thread, we will see, but since you have posted this comment on the Shoreham thread, rather than elsewhere, can I take it you are aware of the
Shoreham accident pilot's background, experience level and licence held?
