It really was a good ole' internet argument where he was just obnoxiously wrong in his interpretation and remained just as confidently incorrect the entire time.
7zip doesn't have a builtin gui on Linux. Your file manager's "compress" and "extract" functions should be able to utilize it as needed. Only power users need all the bits and dials beyond that, and they can use the terminal to harness all the power of the 7z command.
Not to invalidate your experience but I have never seen one with screws yet I have never heard of a back cover accidentally popping off (aside from extreme falls). My current one isn't removable but each one before this was, and I would for years fidget with it by popping the cover on and off, and even after that it held on just fine. Though screws would regardless be more secure and that is good, I agree.
