Can anyone explain the exorbitant prices of some marketplace addins?

One extreme example is Routing & Optimization (by Geotab). It was already outrageous at $55/vehicle/month, but now it's $108/month/vehicle. That will be over $1000 per month with a tiny fleet of 10 vehicles, just for that one addin.

Disclaimer:

• I know that components are expensive right now due to many geopolitical and Ai infrastructure requirements
• The industry, as a whole, is extremely wasteful due to poor planning and lack of visibility into important operational metrics
