The point remains that the article says Yeshua kept the Mosaic Law, where this demonstrates that, in this important inatance, He did not (at least in terms of plain meaning). One could cite Rav Shaul's teachings about what is done in love per G-d's instructions (as opposed to rigid or self-righteous compliance), but that's dancing around the question with regard to the tenor of the article.
You fail to read everything. Jesus and the disciples at the time had to follow all the laws, both ceremonial and doctrine because Jesus had not yet died and freed us from them.
His teachings though are there for us to learn from. Thorough His sacrificial death and resurrection we are free from the Law, and those teachings I shared prove it.
