Sounds like The Old Course needed a Master Plan.
Seriously, who are the stakeholders here, and why were they not given a say in any of this? I'd posit that the the stakeholders include, first of all, the townsfolk of St. Andrews, followed by avid golfers worldwide who've made it a priority to visit the course and learn from it, followed by those who have studied and loved it from afar without yet being able to make the pilgrimage, followed by those who see it and use it as nothing more than a venue for high-level competitive golf events.
If golf clubs all over the world with little architectural merit and almost zero historical significance have nevertheless seen fit to adopt master plans to prevent their courses from being altered by the whims of the current green committee chairman, why on earth hasn't The Old Course been protected in a similar manner?
It's too late to stop this travesty, but clearly a more responsible and deliberate group than the R&A or the Links Trust should be formed to protect the interest of the course and the vast majority of its user. I'd suggest a thorough documentation of all the changes to the course throughout the Open Championship era, choosing a version of the course that best represents its historical apex, and defending what's left of that with extreme tenacity.
