I mostly used Ubuntu based desktop distros and frequently had issues with the 6 monthly update cycle. Problems with Fedora too. I have not had a single update issue with Manjaro. I often have different distros running in VM’s and whilst Arch has been the most reliable, most are not.
I also setup loads of Linux servers in my I.T. job that I used to have, so I have plenty experience.
The bottom line is Manjaro desktop has been ridiculously reliable for me. Therefore other peoples hate of it washes over me and is meaningless.
There isn’t a source. It’s nonsense. Someone was arrested for encouraging violent rioters in the summer in English cities, and rightly so. It wasn’t a protest. It was violent, unruly behaviour by abhorrent thugs. This person sounds like someone who believes everything Elon Musk and Nigel Farage tells him.
