They shouldn't take proactive measures to prevent you from opening the device (i.e. gluing it shut), and should in fact take proactive measures not to (i.e. using phillips head screws). There are lots of little things they can do to make it easier without compromising on the design.
Despite that, I don't think requiring specialized tools is a problem so long as they are (1) generally available and (2) reasonably priced.
Simply because there's like 3 or 4 other types out there which look really, really close to a phillips, but aren't. They have slightly different shapes, and use different shaped bits/points on a screwdriver. Some are compatible with each other (but none are compatible with all!) - and others, if you use the wrong driver on the wrong screw, will tend to strip it out, or cam out with damage to either the screw, the tool, or both.
There are much better yet still easy to obtain drive profiles out there to use for screws (torx is one of them).
