I recently took up Bazzite from mint and I love it! After using it for a few days I found out it was an immutable distro, after looking into what that is I thought it was a great idea. I love the idea of getting a fresh image for every update, I think for businesses/ less tech savvy people it adds another layer of protection from self harm because you can't mess with the root without extra steps.
For anyone who isn't familiar with immutable distros I attached a picture of mutable vs immutable, I don't want to describe it because I am still learning.
My question is: what does the community think of it?
Do the downsides outweigh the benefits or vice versa?
Could this help Linux reach more mainstream audiences?
You're definitely out of date on your knowledge then. Nothing inherently insecure about any of these. Only download software you trust, just like you should be doing with any software format!
I don't really know what you're saying. Most software is distributed as binaries, that doesn't make them inherently untrustworthy, you just need to have trust in whoever is distributing it. It's trivial to look at the build process of a flatpak and verify that it is legitimate. Just because the binary isn't being built from source by every user doesn't make it insecure.
Flatpak is completely open source software and any proprietary software in it has a large warning about how it's proprietary. I don't know why you think proprietary software vendors are pushing these. Ublue, NixOS, and Fedora Silverblue are all community run, not being pushed by some malicious group pushing proprietary software.
Why companies even have anything to gain from their proprietary software being in a container? All that would do is make data collection more difficult.
Go back and look at all the good faith replies to you, and notice that you haven't replied in kind. You seem like you have a strong and incorrect agenda to push, without being willing to take on any new information which people are providing to you.
You only harm yourself by being fixed in your mindset. There is a very strong correlation between success and people who are able to take on information and grow.
I can see where you're coming from because of outdated libraries and flatpak sandboxing not really being a thing (it's an illusion, really) but you can't deny that this is the direction we're moving in, and we need to get flatpak sandboxing and permissions right, to ensure a proper base level of security.
For those unaware:
Many flatpaks use older, outdated, or end-of-life libraries
Flatpak permissions are messed up because most applications ask to bypass the sandbox at install-time
