Speaking of keeping costs down, doesn't CBS have an incentive not to invite every Tom, Dick, and Hannah who's posted online about tardigrades, or fungus, or tardigrades and fungus sometime before DSC went into production to sue CBS on the expectation that they can get a settlement? Why should CBS settle, if they think they can actually win?
I'm wondering if CBS may take the track they did in another recent copyright case. A photogrphaer sued CBS for copyright infringement and CBS then went all through his social media, found a time he posted a picture from gunsmoke, and then counter-sued him.
CBS can get nasty in these kind of cases.
Also just as a point of information, the same law firm is handing this case that also handled the case where CBS sued the idiot that built a for-profit studio off star trek IP.
