Spanish scandal?: Gaudi Chapel "desecrated"

Among other things:

They describe the cleaning of the building as “brutal” and say that it was carried out with abrasive materials abandoned years ago by the conservation industry. They also say that a staircase which provided access to the roof has been removed and they say that the restorers have placed a large stone plinth commemorating their restoration inside the chapel.

I have no idea who is right.
