I run a fairly ancient RedHat Enterprise 6 on my 32-bit test machine and if I need something requiring Gtk3 (such as a latest Firefox or Chrome), I just make a chroot and use debootstrap (from EPEL) to get me a Debian 9 userland for that program. Easy. No bizarre "app stores", no conflicting packages. Do people use Snap app-stores because they don't know how to use the chroot command? Or are they just lazy? If it is because they want the added security of a container, substitute chroot with lxc... Shouldn't be necessary though; if you avoid non-ethical software (i.e App-stores), you are very unlikely to need the added security.

but that doesn’t mean that confining applications is not a benefit also to FOSS applications, security is an issue that needs to be addressed with many layers of measures no mater what licensing approach you use to license the software

However there’s more benefit of confining proprietary closed source applications, because they are to audit to the same level

The benefits for developers do reflect on benefits for users, with more software delivered faster and more securely.

These creeping changes help us forget how important our privacy is and miss that it’s being eroded.

If you have worked with emails before, the idea of placing a script into an email may set off alarm bells in your head! Rest assured, email providers who support AMP emails enforce fierce security checks that only allow vetted AMP scripts to run in their clients. This enables dynamic and interactive features to run directly in the recipients mailboxes with no security vulnerabilities! Read more about the required markup for AMP Emails here.

They don't have to host the extension on their website, but it's absolutely and utterly unacceptable for them to interfere with me choosing to come to github and install it.

Much as it is not the criminal defense lawyer's place to judge their client regardless of how guilty they are, it is not the doctor's place to force experimental treatment upon a patient regardless of how badly the research is needed, and it is not the priest's place to pass worldly judgement on their flock, it is not the programmer's place to try and decide whether the user is using the software in a "good" way or not.
