Since you can't be bothered to post the relevant part yourself, I'll do it for you:
"Courts struck down anti-SLAPP laws in Washington and Minnesota, and Washington enacted an updated law
Courts in Washington and Minnesota struck down their states’ anti-SLAPP laws, finding them unconstitutional under their respective state constitutions. As discussed above, however, Washington enacted an updated anti-SLAPP law in 2021 that addressed the concerns of the state supreme court.
In 2016, a Minnesota appellate court similarly found that state’s anti-SLAPP law unconstitutional, finding that the law “deprive[s] the non-moving party of the right to a jury trial by requiring a court to make pretrial factual findings to determine whether the moving party is immune from liability.” Mobile Diagnostic Imaging v. Hooten, 889 N.W.2d 27, 35 (Minn. Ct. App. 2016). The following year, the Minnesota Supreme Court agreed, finding that state’s anti-SLAPP law unconstitutional as applied to claims alleging torts because it requires a district court to make pretrial factual finding in violation of the plaintiff’s right to a trial by jury under the Minnesota constitution. Leiendecker v. Asian Women United of Minn., 895 N.W.2d 623, 637–38 (Minn. 2017). These decisions raise concerns that courts in other states that recognize a plaintiff’s right to a trial by jury may follow suit."
From that, I don't know that it's reasonable to conclude that "they likely can't protect Sweeney at all", but IANAL.
It is obvious to anyone with even a passing interest in American law that a statute that has already been struck down twice is unlikely to survive a third challenge. Whoever doesn't understand that has a bunch of Wikipedia pages to read before discussing anti-SLAPP laws.
