The NYT accused the FCC of falsely asserting that it didn't have the "technical capacity" to fulfill requests, and of providing "shifting rationales" each time it shot down demands for information. Lawyers also asserted that the FCC was misusing the FOIA's privacy exemption to "duck the agency's responsibilities" under the Act. To back up its case, the paper cited the FCC's dishonesty around the comments, including its false claims of a DDoS attack.
There's reason to suspect Russians might be involved, according to the NYT. They pointed to a GroupSense report tying the 13 Russians indicted over election meddling (plus three companies) to the emails used to submit bogus FCC comments. It's "plausible" that the email addresses involved in these breaches were scooped up and put to use for purposes like this, the NYT said.
Don't expect the FCC to have a change of heart any time soon. The Commission told Ars Technica in a statement that it was "disappointed" in the lawsuit and insisted that that the logs would jeopardize the FCC's security practices. It referenced a recent DC federal court ruling that spared the FCC from turning over those logs under the FOIA. However, it's not being honest here -- the person making the request didn't narrow the scope of their ruling, and the court still asked the FCC to help release the files. The NYT could still have a case, even if it doesn't get as much data as it would like.
