Because the EIN is listed on the W-2, which is filed as part of the return.
And if you're going to reply that you meant some abbreviated form of the tax return, then:
The "what have you got to hide" class of arguments you're using to insist we expose an abbreviated version would also apply to expanding the abbreviated version to full disclosure. And you might be reasonable enough to stop, but that doesn't mean others will be.
People have strong motives to want to dig into political opponents or people they don't like, and we know from history the "what have you got to hide" question and friends are routinely used in trying to eviscerate 4A and 5A rights.
