Yeah, if we conservatively say 1% of InReach users will need to send an SOS message, then looking at the math:

Today, 100 InReach subscribers nets Garmin around $144/yr * 100 people = $14,400

If the InReach were free except for when activating the SOS, the SOS would have to cost $14,000 to make that same revenue from the same number of users. This would surely lead to more deaths due to folks waiting way longer to send an SOS.

Numbers are estimates but the order of magnitude shouldn't be too far off.
