The superfamily spans ligands with distinct roles across development, tissue maintenance and metabolism. They share structural features and signal through related receptor machinery, which is what makes them a family and also what makes selective tools difficult.
Follistatin binds a subset, with affinities that differ between members. "Follistatin blocks TGF-beta" is therefore too loose to design an experiment around.
Because the effect comes from sequestration, it depends on what is available to be sequestered. Two tissues expressing different family members will respond differently to the same addition, and neither response is the compound behaving inconsistently.
What a given system contains therefore determines what the addition can do in it.
A claim naming neither target nor system is unfalsifiable as stated. The primary literature is specific about which ligand, which model and what was measured.
