If you read the Guardian article, Gail Slater did exactly the job Andy Yen said she would when he praised her as a pick for the antitrust chief role.
She's tried to block a $14b merger between Hewlett-Packard and Juniper Networks stating their business sector is far too consolidated already "and would create a duopoly", among other positive antitrust actions.
She was an objectively good pick for the role, and is now being ousted because she's doing her job too well, and that's awkward for Bondi and Trump as they want to have the freedom to rubber-stamp any merger they like, once the tolls (contributions, concessions, no doubt direct bribes we'll only later find) have been paid.
His other statement that you highlight has also been proven to be factually accurate. Big tech has been tripping over their dicks to kiss the Trump ring since before the swearing-in, and continue to do so every day.
If anything, the only response due is a "yeah ok, our bad, we blew this all out of proportion and context" from all the rabid anti-Proton weirdos.
