It would be impossible to buy a company as a steward. We worked with them. In the early 2020s, their teams were as lazy as IBM boomers. Happy to hop on a call, but let's do an rain check or whatever and come back to you after 17 weeks to say no in an email CCed with 42 people playing hot potato between commercial people who try their best to sound technical.

My money is on holding companies like IAC buying the brand first through financial engineering and restructuring finances initially. They would load it up with debt like they did with the sporting goods store in Sopranos.

Afterward, they would sell it to a Euro-based caretaking company like Bending Spoons, with a focus on maintenance engineering rather than innovation engineering.
