Those users will either check the source code and compile it themself, with all the proper options to match their system; or rely on a software distribution to do it for them.

People who are complaining would prefer a world of isolated apps downloaded from signed stores, but Linux was born at an optimistic time when the goal was software that cooperate and form a system, and which distribution does not depend on a central trusted platform.

I do not believe that there is any real technical issue discussed here, just drastically different goals.
