The museum only decided to start encouraging the egregious behavior after the flats were built. The museum knew the egregious behavior by their guests was taking place and did not intervene until forced to do so by the courts.
I really don't see how you can read through the court judgements and not arrive at the conclusion that the Tate just really went out of their way to look cartoonishly evil.
Actually, sounds like they had a much better solution than moving out of the city: they appealed to a judge, who agreed with them. Sounds like you’re the one out of step with reality here.
