I think Google is headed to breach the trust thermocline (warning: a twitter link). I think why these collapses seem sudden and so large in scale is because there's so much inertia. Services / products that have become the standard can go well below the line that would be accepted otherwise and that's why they don't see big changes in user base while the enshittification process goes on.. So, for them the point where a large portion of the user base is even willing to try alternatives is already way too far.. and no small corrections is going to cut it. They try to find out what they did in the last months to cause this exodus but the reality is that they've been worse than competitors for years.
