Proprietary Means Not Secure
There's this bunch of reports about so-called security cameras which end up being a security risk or a liability. Basically, those are configured to be not secure or don't receive updates despite being connected to the Internet. Some folks point out the obvious or use the famous old joke: "The S in IoT stands for "Security"."
This is "the direct effects of proprietary software," argues one person, seeing that since Linux gets thrown into a device without disclosure and without ever being updated (a possible GPL violation) we may end up with millions of devices configured to use the same default password, which cannot be changed either. The Linux Foundation contributes to this problem by fronting for GPL violators. If those companies worked "upstream", these devices would be easier to 1) audit and 2) patch.
Proprietary software tends to rely on secrecy, not good design. And secrecy is only ever temporary. █
