Because it was wrong, his own former student, rutherford proved him wrong.
J. J. Thomson's scientific ideas were called the "plum pudding model" or the "Thomson model." This model proposed that atoms were composed of a positively charged material with negatively charged electrons embedded within it, resembling plums in a pudding.
j.j thomson put forward the plum pudding theory according to which element is like pudding of positive charge and tiny negative charges stuck inside like plums in pudding.

Some scientists who opposed J.J. Thomson's atomic theory included William Prout, Ernst Rutherford, and Max Planck. These scientists challenged aspects of Thomson's model, such as the presence of subatomic particles within the atom.
Joseph John Thomson.
J. J. Thomson discovered the electron and the isotopes.
J.J. Thomson's discovery of the electron showed that atoms were not indivisible as Dalton thought, but were made up of smaller subatomic particles. This led to the development of the plum pudding model of the atom, which replaced Dalton's solid indivisible atom theory.
