As engineers and designers, we should side with her on this one. The core conceit of McMansion Hell is that these are this homes built without experts, particularly architects (but any kind of designer is absent from them). These are often big, expensive homes, where the builder and the buyer thought they didn't need the help of an actual professional.
This isn't just an American thing, but it seems particularly bad here. People spend a lot of money on homes, but try to cheap out as much as possible in expertise. No architects, no designers for the interior, no landscape architects for the yard (many greenfield McMansions are delivered with zero landscaping!) and even sometimes skipping electricians and other skilled tradesmen for upgrades and additions.
Post college I had a mentor that was in the real estate development business, not for McMansions, first time homebuyer and some developments in the next price point up (<$500K) in a major metro so I got to learn quite a lot about how this works. I am no fan of McMansions although my primary complaint is that many of them are just built so close together, not that their aesthetics are particularly bad. The style of home that I would build is not typically built by major developers like KHov or whoever.
Houses are a bit like software. Builders will typically have base plans and then depending on the price point a varying number of customizations that can be applied. The more expensive the home the more customizations offered. A really great thing about people buying McMansions is that they are all experts and know far more about building a house than someone who literally owns a company that does this. So people who sell to this demographic let the customer do a lot of driving especially on the interior. Builders can also mark up these customizations to increase margins. So really I guess bottom line here is that people want these houses. The architecture (or lack there of depending on your view) is carefully researched to appeal to people with the right amount of money to spend. Having watched this process from the builder side there seems to be little to be gained from trying to for design on to the customers as they don't want it.
I think it's a bit forward for criticizing the purchasers of these homes for the aesthetics alone. They wanted these homes and there is going to be someone who will provide it. I am yet to find modern art that I can appreciate but I am happy that others can. I love classical sculpture which I am sure someone would have a bit to say about if I stuck one in my house. If someone wants a non-functioning balcony (this I just cannot understand) to each his own. One nice feature these homes have is that they are all built together in large developments where I will rarely ever venture.

I guess I'd argue that the aesthetics are bad for the reasons the blog in question points out--lack of unifying design principles, etc. At least to my eye.
However, I also agree with your point about space. This may not be popular with the density crowd, but a few acres with lots of trees and other landscaping hide a lot of architectural faults. Cram big houses assembled from random architectural styles on a half acre with just a garden or two and it's not attractive.
I think you bring up an important point: there is a class of homebuyer who is both wealthy (or at least high-income) and a control freak. McMansion (or more specifically McMansion builders) target this demographic with empty shells, then let the homebuyer customize to their heart's content (even if said customization is stupid).
For some, it appears that the control is an important purchase consideration. The bank is the only one taking the risk.
A lot of times such houses are built by large homebuilder companies. They employ architects and landscape designers. Why does it still seem like things are in such poor taste? Maybe it's because that's not what people want to buy.
