That kind of blanket statement is not only factually wrong, it does no one any good.
Almost all food consumed in the world is mass produced, and most staple foods (rice, grain) have been mass produced for centuries now. While we've increased automation in some things, using a robotic metal arm to harvest grain doesn't change anything about how healthy the grain is.
Now what sorts of pesticides are used can change things, but being "organic" doesn't change this, as some of the initial (early 2000s) organic pesticides were found to be horrifically toxic. Each substance applied to food needs to be judged on its own.
The real problem with food designed for mass consumption (different than mass produced!) is that it is engineered to be hyper palatable, so people want to eat more of it. Think potato chips (very few people ever open a bag of chips and have a reasonable number!) or any other "snack" food. Individually the ingredients may be safe (in moderation, and note that plenty of "healthy" foods are bad for you in excess), but when packaged together in a way that encourages over-consumption (and then backed by an ad campaign that does the same), negative health effects start to appear.
And FWIW plenty of "highly processed" foods are healthy, the issue once again comes down to most foods in the highly processed category also being engineered to encourage over-consumption. However things like whey protein are highly processed and healthy.
All that said, eating nothing from a bag or a box or a restaurant will generally improve a person's health, but that is largely due to the reduction in calories.
My first thought as well. This is the most complicated stack I’ve seen for something so simple. Just convinced me more to avoid using JavaScript as a backend
speaking as the project lead for Matrix: I haven’t done a great job of balancing “build new stuff to show off how amazing Matrix can be” and “make current stuff super polished and amazing”. However, we’ve spent the last few years plugging away addressing that, and I’d like to think the situation has improved significantly.
Another consideration is that nobody yet has consciously gone out to build a Discord killer on top of Matrix. Element is currently focused on being a WhatsApp replacement for government users (as a way to bring in $ to make payroll), which often explains why folks expecting it to be a drop in replacement for Discord users have to readjust their expectations a bit. That said, Element could certainly end up competing proactively with Discord in the longer term.
Meanwhile, Matrix certainly suffers from being successful enough to engender very strong feelings from folks who are disappointed in it. Whether that amounts to being run badly is probably a matter of perspective.
