The article's analysis doesn't appear to be accurate. From the bill:

(a) Requirements.—An operating system provider, with respect to any operating system of such provider, shall carry out the following:

(1) Require any user of the operating system to provide the date of birth of the user in order to—

(A) set up an account on the operating system; and

(B) use the operating system.

(2) If the relevant user of the operating system is under 18 years of age, require a parent or legal guardian of the user to verify the date of birth of the user.

(3) Develop a system to allow an app developer to access any information as is necessary, collected by the operating system to carry out this section and any regulation promulgated under this section, to verify the date of birth of a user of an app of the app developer.

The only requirement for "verification" is to enter a birthdate on account set up, and underage accounts have the parent "verify" the birthdate. There is certainly some ambiguity in the bill which is not good, but efforts should be towards resolving the ambiguity in favor of a lack of intrusiveness.
