Yes. I know. But people see posts on the internet about "clever hacks" and don't realize the implications of those hacks or what they are primarily used for. Technically speaking, this is one of those "illegal activities" that I mentioned. It is a copyright violation. Developers can specify whether or not they want to allow their apps to run on the Mac. By default, they are allowed to run. Therefore, if a given app won't run on a Mac, it is because the developer doesn't want to allow it. They wouldn't do that without good reason.
Of course, this isn't malicious or evil. Somebody just wants to run an app on a Mac. They probably don't know about all of the details and potential pitfalls involved.
But the OP's question was about why Chrome and Discord weren't working with SIP disabled. That's the malicious and evil part. I'm sure that both of those apps are disabled under SIP due to malware (on Chrome) and even worse (on Discord). Most other apps would be concerned about software piracy. Pound for pound, software piracy is the primary use case for disabling SIP.
Most people don't encounter this problem because few developers seem to realize how much illegal activity goes on in plain sight over the internet. Or at least, they don't talk about it.
