That crowd are just deeply concerned one of their lucrative revenue streams is disappearing.

So they seem to be attempting to pull a fast one and use unproven claims to try and convert their competitor into a replacement revenue source.

It'll probably be a case of whoever has the best lawyers + contacts + persistence wins.

But it'll be interesting if discovery shows evidence they know they don't have a case and are trying it anyway. "Piercing the corporate veil" can theoretically be a consequence of that AFAIK.
