There is a humor that these law firms won a case against Meta and the first thing they did is give them advertising money won from the court case. That said the ads sound pretty aggressive, and from what I've read it sounds like it wasn't a very fair decision. I understand the conflict of interest but I have sympathies for Meta here

I think these ads were to bait Meta into banning them (which they've done) and now the firm will follow up with a lawsuit because Meta suddenly is able to very rapidly decide what ads get shown if it's going to hurt their bottom line.

I do not have any sympathy for Meta.
