Most of the money spent on product development is likely going to engineers, graphic artists, industrial designers, and other professionals (who are in turn paying tax on their payroll) or to other software/IP vendors (who in turn are paying their own engineers).

Granted, that's probably not as good a use of capital as, say, direct benefits to people in poverty, but it's vastly better than stock buybacks in terms of public benefit.

Yes. You can reach in between the top of the door and the wall with a bent wire, and use it to grab the pull cord that releases the door.

It is difficult to describe, but there are plenty of videos out there showing this method. It is surprisingly easy on some doors once you get the technique right.

For those stumbling upon this comment, there are easy ways to protect your garage door from being opened this way - you can fit a guard near the pull cord to prevent it from being hooked.
