I'd agree that's annoying yes, but it's free. There comes a point where the amount of free users upgrading to premium isn't enough, so they're left with either changing the free service to boost that number or remove free as it likely loses them money. I'd agree that it's shitty yea, but the free product is meant to be a preview to entice premium subscriptions. If they aren't getting enough upgrades, something has to change (in their view)
