it has improved, but I also still hear people mention delayed deliveries every now and then. I suspect it may have more to do with too-tight firewalls on networks hostile to P2P, and perhaps with users experiencing difficulties to contact each other when they happen to both be behind the same CGNAT ,or never online at the same time, than any unreliability of the protocol in itself. but the fact that Jami insists on only delivering messages to the final destinations, instead of using third parties as proxies, may make these circumstances seem like flaws

foi um dos dias mais tristes e mais felizes da minha vida. fiquei arrasado com o acidente, mas nesse mesmo dia uma amiga minha comemorou seu aniversário convidando alguns amigos para uma festinha em sua casa. foi o dia em que me dei conta de que estava apaixonado por ela. ainda demorou umas semanas para começarmos um romance, mas rendeu: estamos juntos na parceria da vida há quase 30 anos

I always recommend GNU Jami.
as for reasons, it respects our freedom and privacy, it runs on most operating systems for desktops and mobiles, and it doesn't depend on any proprietary infrastructure that could exploit us, censor us, or otherwise snoop on us and be enshittified? thanks but no thanks, I don't wish to get Zuck (or anyone else) involved in our private conversations. as says a friend of mine, why should I go along with your platform of (poor) choice, that would screw us both, but you can't go alone with my platform of choice, that would keep us from being controlled and screwed with. besides, your platform of choice would require me to carry a tracking device.
that's how I generally respond

I miss the days when the web was for sharing rather than for consuming and controlling.
I miss the days when it was common sense to avoid running code downloaded from strangers. now we have javascrippled websites that won't work unless you betray yourself and common sense
I miss the days when we could automate mechanical/boring web tasks, when remote bots would not refuse to share information with our bots just because we're using bots. now they insist in only talking to humans, turning us into their servants instead of serving us

no free software distro can do that. users control free software.
maybe what you're trying to say is that you don't like distros that don't offer convenience for you to shoot yourself in the feet. that presumed feeling of yours sounds plausible to me, it fits with what you've written. but it's a matter of convenience, not of freedom.

Wheee, tonight I'm flying out to the US to speak about software enshittification and how to fight it at LibrePlanet @fsf

when you celebrate you can decide whether or not to install a certain blob that claims to fix a bug, and that this is some freedom, you appear to be missing that the supplier is denying you the freedom you should also have to see what other changes the blob would bring onto your computer, and to decide which of them you want and which of them you don't, and to improve on them, and to help others. you're celebrating the crumbs thrown at you so that you'll leave the bigger piece of the pie to those who control you.

trusting that the blob suppliers have your best interest in mind when they push updates, instead of aiming to expand their power and profits through the control over you that you grant them, is naïve at best
