As per "Measure of a Man," Data strongly recommended that he "continue (his) work" and that he found some of what he proposed "intriguing." Sounds to me that Bruce was well on his way to establishing non-sentient androids after this episode.
There's a lot to love about this story, but what's so great about it is that Commander Maddox isn't a monster. In the end, we're allowed to like him and it should be like that. He's obsessively barking up the wrong tree, but he's not inherently evil, nor are his attitudes towards Data. They're just misinformed and misguided. And thanks to his own personal journey in this show, he finds illumination. Resultantly, I'm confident that he probably became a champion of android rights, as his own work continued - even if his products never crossed the threshold into Living Beings.
And who knows what the law stipulates, in the fine print, that Phillipa Louvois put into effect.
