Yes, these are press releases which are generally done under the restrictive policies to which lawyers must adhere in regard to advertising.    A somewhat more upscale version of TV's screaming "HAVE YOU BEEN HURT IN AN ACCIDENT!" commercials, if you will --  the press-releases being just one method of reaching potential plaintiffs in the class without directly soliciting them.

None the less, the suits are real, and, if only from the number of firms filing, they appear to have some merit, hence newsworthy here I presumed.
