Because of how awful previous betas were, and how gradual and unannounced the improvements have been, the knee-jerk reaction to "oh, we're going to try redirecting you to beta!" is "OH HECK NO YOU DON'T."
The beta is still terrible, but it is substantially less terrible than the versions I looked at last year. During that time, I and many others gave careful feedback but it seemed like there was awfully little improvement over time. It got to the point that a redirect to beta just instinctively causes panic and anger because people have had such terrible experiences with it in the past.
I'm afraid that in the past couple of days some of the complaints and feedback I've given were no longer accurate for today's beta.
I still think the information density and the comment system have a long way to go. I still think the (thankfully slightly rarer now) stock photographs are uninteresting, uninformative, stupid, uninformative, and a total waste of space.
But at least you're not only using a third of my screen's width for content, making it so only ~3 comments can be seen on screen at a time, etc. like previous betas did. That was horrific. Before you redirect anyone to beta, help them know about what's been improved with beta and apologize for past mistakes.
And for pete's sake, give people the option to switch the silly color scheme. Should be simple enough.
