The availability of that information is probably worse than ~10 years ago, but still better than any time in the past before that.
Another problem is that there are just too many products these days. 40 years ago someone might have 5 options for a vacuum cleaner, period. Someone on the internet today might have 500 options. It's just information overload. Someone who really cares to, might go through the 236 options that Consumer Reports has tested [0]
But most people aren't the type of people who would spend a half-hour arguing about consumer product quality on the internet. Most people aren't willing to spend any time to evaluate their options for relatively small purchases beyond the immediate moment of purchase.

Good information for the quality of cheap consumer goods is hard to find because the information is not particularly valued by most people.
