As discussed previously and confirmed in your snip (redacted), The McCann's were concerned as to the effect Bennett was having on the search, which we assume is negative, so they wanted him stopped.
So they intervened against an old man with a grudge, an incongruous theory and a pushbike, but seemingly overlooked a concerted, well organised Youtube campaign by a man with 1000's of followers.
The difference I see is that Bennett took it to the front door. But in terms of 'damaging the search', they're on different scales.
Low hanging fruit? Pick your battles?
...and aren't they oppo's? Bennett supplied the ammo, Hall fired them?
Not really ...
In my opinion this was "an old man with a grudge" according to you, who had the expertise ~ the knowledge combined with obsession who stole Madeleine's name to confusingly set up the Madeleine Foundation for the express purpose of libelling and harassing Madeleine's parents and asking the public for donations to enable him to do so.
And all at a time when the Portuguese authorities had written Madeleine off and were not looking for her and her parents were desperately highlighting her plight and trying to get an investigation into her case restarted.
And all at a time when the British authorities were being desperately lobbied by Madeleine's parents to start up their own investigation into Madeleine's case and initiate investigations into what happened to her.
There was no official investigation being conducted into the circumstances of Madeleine McCann's disappearance anywhere in the world ... only her parents were looking for her and they knew that wasn't enough.
In their opinion Bennett's libels attacked and impeded their campaign to find Madeleine.
In 2013 Kate and Gerry's ceaseless efforts paid off and a police investigation was begun in Britain, Madeleine's homeland ~ and a police investigation was begun in Portugal, the country where Madeleine disappeared from.
Kate and Gerry were eliminated from the inquiries of both official police investigations ... and both official police investigations which are still ongoing, are investigating Madeleine's abduction.
In my opinion people who are fly by nights who come and go after making their pound of flesh on the conspiracy theory circuit are a total irrelevance at the moment. Madeleine's case is active and being investigated ... she is being officially looked for and that situation has been taken on board and its significance recognised by the majority of people who might have an interest in her case.
The majority know the earth isn't flat. A minority believe it is. Basically they exist on the periphery ... a total irrelevance to most and to some who don't even know of their existence or if they do, couldn't care less about them.
So it is with those who have their fifteen minutes of fame then vanish back into the obscurity from which they emerged.
Madeleine's case is being investigated. Madeleine is being looked for which may well be an irritant for some ... but that is the state of play right now.
