The big problem is that while yes excellent groups do exist doing varieties of investigation from citizen journalism through to in-depth reportage they are, for the most part, totally buried by the dross and misleading work which is lower-cost, more popular, better funded and less likely to attract pile-on takedown attempts. The functional outcome of this form of monetisation is not generally favourable to either us or the balance of fact vs fiction more generally.
I'm not positing traditional commercially funded news journalism as a good model by any means - though I do think the partial collapse of its investigative function, partly fuelled by the shift of ad revenues towards big tech, is a bad thing because as Dispatches itself shows, when it works it has the chops to break through in a way that no amount of YouTube vids can.
