Anti-viruses are a scam and always have been. They aren't much more than security theater and box ticking. Don't get into the mindset that you can outsourse security to a single product. Security is something that happens in depth. The more intrusive av software can itself become an attack vector as it often runs with lots of privileges.
Distros operate with webs of trust and cryptographically signed packages. Your distro installer verifies the integrity of the package. There is no need to check a third party signature database. It adds no value. Even well audited software could contain hidden vulnerabilities so increasingly we are running software with less capabilities via systemd, flatpak/brwrap or in containers. The environment is very different to the origins of av software on Window 9x where people would download random unsigned executables to a system with no privilege restrictions.
There are lots of challenge for the FOSS community. We love features and freedoms and those features and freedoms sometimes make security more complicated. We need to show more restraint packaging software like ssh and not add so many patches and additional dependencies. We also need to show more restraint in the typical rust, go or javascript project where adding dependencies is so easy we end up sometimes including hundreds of them for stupid crap like coloured messages or being able to handle a dozen config file formats. I don't care about your garbage collection or advanced compile time checks, if you include hundreds of crates from other developers you are no better than npm and I would put more faith in a 20 year old c library.
I apologise for the language but I am fed up with this shit.
I don't think promoting OpenAI/Microsoft services is very compatible with the open source/free software ethos.
OpenAI pretend to be a non-profit but are controlled by billionaires and Microsoft. I am not going to take up a subscription and have my personal data mined by a company so I can have the arch wiki and man pages developed with millions of hours of volunteer labour served back to me.
I used to attend Linux/free software conferences decades ago and there would always be that one person who thought Facebook or Google were brilliant and that adding everyone's lives and personal data to gmail or facebook was totally fine because the APIs were cool and big companies are totally ethical, "Don't be Evil" etc. I thought they were foolish then and I think time has shown they are even more foolish now.
Every news site and forum I go to, even very non-technical ones, has people appear out of nowhere exclaiming with enthusiasm how OpenAI/copilot solved all their problems in great detail. Whether they are genuine or are just on the hype train created by bots and paid influencers I am at my breaking point with this shit. It is worse than the crypto bros with their NFT monkeys and get rich schemes. It has nothing directly todo with Linux or open source software. I escaped reddit to avoid all the influencers and people peddling shit but it is here as well and people can't see it for what it is.
