Proprietary SabotageOther examples of proprietary malware
Here are examples of proprietary software that has something worse than a back door.
Google has long had a back door to remotely unlock an Android device, unless its disk is encrypted (possible since Android 5.0 Lollipop, but still not quite the default).
This seems to involve use of a back door in Windows 7 and 8.
Lenovo stealthily installed crapware and spyware via BIOS on Windows installs. Note that the specific sabotage method Lenovo used did not affect GNU/Linux; also, a “clean” Windows install is not really clean since Microsoft puts in its own malware.
Microsoft is repeatedly nagging many users to install Windows 10.
Vizio used a firmware “upgrade” to make its TVs snoop on what users watch. The TVs did not do that when first sold.
Amazon downgraded the software in users' Swindles so that those already rooted would cease to function at all.
We can be quite sure this EULA is is unjust because injustice is the only motive for imposing an EULA.
FTDI's proprietary driver for its USB-to-serial chips has been designed to sabotage alternative compatible chips so that they no longer work.
Microsoft is going to cut off support for some Internet Explorer versions in the same way.
A person or company has the right to cease to work on a particular program; the wrong here is Microsoft does this after having made the users dependent on Microsoft, because they are not free to ask anyone else to work on the program for them.
The NSA has put back doors into nonfree encryption software. We don't know which ones they are, but we can be sure they include some widely used systems. This reinforces the point that you can never trust the security of nonfree software.
An Apple firmware “upgrade” bricked iPhones that had been unlocked. The “upgrade” also deactivated applications not approved by Apple censorship. All this was apparently intentional.
Some proprietary games lure children to spend their parents' money.
Adobe applications have time bombs: they stop working after a certain time, after which the user must pay to extend the time.
Once there was a problem with the servers that these programs use to check who has paid, and the applications refused to work for anyone.
Sony sabotaged the Playstation 3 with a firmware downgrade that removed the feature that allowed users to run GNU/Linux on it.
Sony subsequently sent police after Geohot, after he cracked the code that blocked users from changing the firmware, and we responded by calling for a boycott of Sony .
LG disabled network features on previously purchased “smart” TVs, unless the purchasers agreed to let LG begin to snoop on them and distribute their personal data.
Oracle's nonfree Java plug-in for browsers sneakily installs other annoying proprietary software.
That article disregards all other bad things about proprietary software. For instance, it regards the inclusion of proprietary Flash Player (which has a surveillance feature and DRM) in Chrome as a good thing. Chrome is a proprietary browser with a universal back door.
We don't agree with the article's views on those issues, but we present it as a factual reference.
