… and so am I.
When you develop software, you will always be reliant upon platforms. You use their interfaces to make your hardware do stuff. People who maintain these will almost always do so with certain conditions. In iOS's case, you must have all of your content certified by Apple before it can be installed. In Linux's case, if you make any changes to the platform and distribute them, you need to also release what those changes are.
Sometimes, they are enforced with copyright law. Recently, some platform vendors use chains of trust with strong, mathematical keys. This means that, unless Apple, Microsoft, Oculus, or whoever else made a mistake, members of society can be entirely locked out of creating and installing content.
This has pros and cons.
On the one hand, it can be used to revoke malware authors, scammers, and so forth. These platforms, being more compact, are usually easier to develop for, and might even be portable across deeper platforms, like x86 or ARM.
On the other hand, it can be used to revoke anything else. Imagine that you live in a jurisdiction where the government wants to ban encryption software. Imagine you live in a jurisdiction where the government wants to ban art featuring characters who are LGBT. Imagine you just want to use your hardware in a way that the vendor does not support, such as our attempts to measure UWP application performance.
We need to be extra careful when dealing with good intentions. These are the situations where people will ignore potential abuses because they are blinded by their justifications. This should not be taken lightly, because when you build something, you build it for everyone to use and abuse, intentionally, or even blinded by their own justifications, which often oppose yours.
For art and continued usability, Microsoft, Oculus, and everyone else needs to ensure that their platforms cannot be abused. They are not a government, and they have no legal requirement to grant users free expression, but these choices can have genuine harm. As owners of platforms, you should respect the power that your platform enables society to wield, and implement safeguards so that you can continue to provide it going forward.
