> They have no desire to unseat BigTech, they want to be acquired by them.

Acquisitions are one way to make money off big tech. Breaking them up and buying parts of them for cents on the dollar are another, especially if you can issue barely veiled threats of government-backed retaliation if they refuse to come to the table with your allies/fronts. With a "loosened regulations" regime, IPOs may be even more profitable than acquisitions.
