A possibly better analogy would be if a ride-share gave you a free ride to a concert and all of your friends have used that free ride without issue but then the ride-share company forced you out of the ride halfway to the concert without warning and said "should've read the fine print not our problem!" - now you're possibly in a bad neighborhood with a dead phone battery in a much worse place than you would've been if you never trusted the free service to begin with (and I would suggests it's not hard at all to imagine a scenario with more dire consequences in this situation)
If people are planning their near future based on what you've said you would likely be giving them, then at some point there is probably some inherited responsibility to at least give the user of that service a heads up so they can make other plans if possible.
