Well, over at Taiwan Journal, Mark Caltonhill has arrived to set us all straight: we tongyong haters are a bunch of colonialist shits:
HP supporters, through, often argue that using tongyong pinyin would be no more useful an expression of national identity than requiring people to wear their underwear on the outside of their clothing. Difference for its own sake makes Taiwan look petty and ridiculous. Taiwan does not benefit from looking ridiculous.
It is hard to see this concern for Taiwan as genuine. More likely it belongs in the same category as the we-know-what's-best-for-you mentality of Christian missionaries proselytizing their religion, and "English teachers" qualified with nothing more than a white face telling Taiwanese they need native-speaker pronunciation.
This kind of thing is just shake-your-head stupid. I don't think there is any need on my part to comment further. Wiki actually has an entry on this fellow, who is apparently a long-time resident of the island and has written a large number of articles in local magazines and newspapers.
