Do you see much difference between ether, which is presented everywhere in our Universe, and Higgs field, which is presented everywhere in our Universe? Quote from your link:

«To justify giving mass to a would-be massless particle, scientists were forced to do something out of the ordinary. They assumed that vacuums (empty space) actually had energy, and that way, if a particle that we think of as massless were to enter it, the energy from the vacuum would be transferred into that particle, giving it mass.»
