IRS poking into nonprofit web sites?

As part of the Telephone Excise Tax Repeal Act of 2005 (S. 1321), that "friend" of nonprofits Senator Charles Grassley (R-Iowa) added some provisions regarding what nonprofit organizations must disclose.

According to page 124 of "DESCRIPTION OF THE CHAIRMAN'’S MODIFICATION":

"The proposal requires a tax-exempt organization subject to reporting requirements under
section 6033(a) to include on its annual return any name under which such organization operates
or does business, and the Internet web site address (if any) of such organization."

Apparently, organizations who file IRS 990 or 990-EZ have had to report their web address previously, but not so with organizations, mostly very small nonprofits, who file informational returns (IRS 990-PF).

We see this as further allowing the camel's nose under the tent flap. What business is it of the IRS, or Senator Grassley, what web sites a nonprofit operates?
