Yep, you should definitely be wary about joining a startup in a drying industry, like B2B. Ask yourself if the customers/clients of said startup are still able to afford spending money on the product. If the customers themselves are another tech company that is struggling due to their VC money going away, probably not the best choice.

Why is B2B dying now, as opposed to previous tech recessions?

Not dying, just drying up and I'm sure there will be a resurgence. If you look at the companies doing layoffs, the majority of them cater to other tech companies who all seem to be pulling the purse strings tighter.
