It only says that he argued against it for five hours in the state house. It doesn't explain why he opossed it?
You must have overlooked the introduction to this article.

"James Otis, Jr. (February 5, 1725 – May 23, 1783) was a lawyer in colonial Massachusetts, a member of the Massachusetts provincial assembly, and an early advocate of the Patriot views against British injustice that led to the American Revolution. His catchphrase "Taxation without Representation is Tyranny" became the basic Patriot position."
