I find it interesting how many companies are attempting to use the flexibility of open source technologies to make up for the many shortcomings of Windows. Open source technologies are becoming more attractive for alternative solutions not just because they're generally more secure out of the box, but the ability to combine the many different features that are available provide a level of flexibility in which Windows could only dream. For instance, the use of immutable Linux distros, such as UniconOS, makes it much harder for a valid user or an attacker to damage or compromise the system. In addition to that, in Linux it's possible to combine file systems that can take snapshots (ZFS, Btrfs, etc) with boot loaders that can boot from specific snapshots to easily revert back to a usable system after a botched update (I bet the sysadmins who had to clean up after the Crowdstrike debacle would have appreciated that option!).
Meanwhile, Windows stagnates with no viable options to compete with these technologies. It makes we wonder if Microsoft will ever even attempt to catch up or just continue to slowly cede functionality to Linux and other open source alternatives. I'm not suggesting that Linux will take over any markets, but if I was running a company I would do everything in my power to make my users forget that competition even exists, not let my products stagnate to the point where the market becomes desperate to explore every possible alternative.
I don't expect this product to be particularly popular, but I do find it interesting that Citrix recognizes the problem and is attempting to use open source to resolve it.
