It depends upon how you look at it. Something like the Raspberry Pi is considerably more expensive. On the other hand, they started with a very low performance and weak feature set and have evolved into a product with good performance and a much richer feature set. Something like the Raspberry Pi Zero is much closer to the original Raspberry Pi, and its price is much closer to the original Raspberry Pi. Much of the price bloating features were a product of customer request. To be fair, they dropped many hints that it would increase the cost of the product.

From my understanding, support has also improved over the years. Raspberry Pi always had a bit of an edge in community support, but they also had a push to develop free resources for education markets and hobbyists. The former has been traditionally been a high-priced add-on. The latter has traditionally been provided by third parties (more reasonably priced, but still at extra cost). None of this has disappeared, though it does appear to be less prominent than in the past.

I think the big change is in the competition. SBCs were traditionally high cost poorly supported products or even higher cost well supported products (though you were unlikely to get support unless you were a business). Now we have a flood of low cost poorly supported products, albeit with slightly higher standards for support than in times past.
