In spirit i agree with you.

In practice the problem here is, to use a really crude analogy:

The Cerebro developers rented an empty mall for super cheap, then opened a single restaurant in it. Some people won't mind driving all the way there and walking through the entire thing to get to the restaurant, other people will.

The advice then in that situation is to one of these:

1. Demolish the parts of the mall that aren't used, piece by piece, while trying to not knock over the restaurant situated on the third floor, so other people can build their houses on the now free space, closer to the restaurant.

2. Abandon it and build a new restaurant in the middle of the city.

Everyone recognizes that both of these are very expensive solutions and unlikely to ever be implemented, so you end up with two kind of people.

1. Those who shrug and walk away saying nothing.

2. Those who go, with various amounts of emphasis: "Aw, i wish you hadn't done that."

There is no happy middle ground possible here, sadly.
