Because a diff is not intelligence. The hard part is not fetching a pricing page every week, it is knowing that this particular change matters and the other eleven do not, then saying so in three sentences a founder can act on before a Monday call. That judgement lives in accumulated history and a lot of tuning against false positives. It also survives being ignored: a brief that arrives whether or not you remembered to look is worth more than a script you stop reading in week three.

What do I lose by replacing Debriefing?
Honestly: noise filtering, which is the actual product: most diffs are rotated testimonials and changed asset hashes, not competitive moves; horizon watch, meaning the substitutes and new entrants you did not think to add to the list; the non-page signals stitched into the same brief: hiring, funding, traffic and LinkedIn movement; the analytical step from what changed to why it matters to what to do next; an archive going back far enough that a change reads as a trend rather than an event. If any of those are load-bearing for you, keep paying.
