Personally I would not move out of the way just out of badness. If they asked politely I would pull over at the next opportunity.
I’ve caught people before while recording my ride but it happens and it’s not an issue, I don’t usually ask them to move either I just ride behind at their pace, most folk are polite enough to pull over when they feel safe to do so, and that is just fine.
Don’t blame Strava for idiots behaviour either, an idiot on the trail will be an idiot with or without it and they were probably a knob well before Strava was about. Plenty of folk record their ride without feeling like they have to race every ride.
