Garage doors are not high security devices. Hackers on the internet are the least of your concerns. If someone is going to break in, it's the idiot down the street with a crowbar, not a nerd 3 states away.
The nerd 3 states away is not going to break in. The script kiddie 3 states away running a bot and opening garage doors en masse for the lulz is going to be a problem. Especially if the random idiot from down the street gets your ebikes without using a crowbar, because he passes by in the right moment.
Imagine someone opening the garage doors of every house that has this installed. The fact that physical access is needed to open the door, legally or not, is a good thing.
