That’s…a gross oversimplification. Super popular open source projects tend to have few bugs from the sheer number of contributors available to fix them, but active proprietary software has dedicated teams working fulltime every week to deal woth issues. Proprietary stuff is often way wider in scope than open source, so more surface for bugs to creep in. Scope and team size have a lot more to do with bug density than open vs closed source.
In general it is. Opensource software has less bugs that proprietary. And even those bugs can be mitigated with hardening.
