And the old broken record says that what isn't broke don't fix it. Your UX is 100% subjective. My UX is 100% subjective. Who's right? You're asking a redundant pedantic question. Do people disagree? Absolutely. Are there overall industry trends regarding UX/UI's? Some notable general trends:
1. Mobile friendly design
Companies are seeing large numbers of their users going to mobile platforms to consume their content / activities, so all UX/design are being shoe-horned to support mobile friendly designs. Why does Google+ on my desktop browser have the hamburger menu? Because it works for mobile and we're eating their crow. This has bled into many desktop offerings, which is largely why you see UX/UI hostility on Slashdot. People here seek configuration / customization unlike the majority of the 'user' market you're catering to.
2. 'Responsive' designs
This one goes along with #1. Easier production of services / products on any number of devices by using frameworks (or rolling your own) tooling that allow for simpler content production flows.
Its been around longer than 5 years, but the idea that UX / features can change overnight has largely been accepted by the masses. Regardless of the goodness of the release, people are a lot more tolerant that 'things won't like the same' than they used to.
If ANYTHING that's universal about Slashdot people: They hate being lumped in with the masses, and frankly that's not necessarily a bad thing to fight for.
Why don't YOU tell the room the most amazing and innovative UX/UI enhancements in the last 5 years? You tossed the stone, so please enlighten us as to all-in design updates that make everyone's lives easier. Trust me, if there was an objectively better experience that doesn't remove features (many would still complain but that's life) people will love it.
