Was There Pushback for the Schumer Amendment in the Senate, like in the House? If Not, Why Not?

I may not understand how this works, but hopefully somebody knows:

When the Schumer Amendment was sponsored and put into the NDAA for the Senate version, why wasn’t there pushback then? Is anyone aware of dissent in the Senate over the Schumer Amendment at that time (June to July)? From where we stand, it seems like they just kind of passed it. Why would they do that?

There are plenty of Senators who suck just as hard on the contractors’ teat as in the House (cf. Schumer’s own donors!). Does this betray that the contractors and DoD/IC–for whom Congress is definitely the mouthpiece–weren’t unified or were schizophrenic on this issue at that time? I think it’s reasonable to think that the contractors’ lawyers would have been aware of the Schumer Amendment’s appearance and its implications. Additionally, why didn’t the IC try to stop it then, despite the SSCI Chair and Vice-Chair being friendly to the issue?

If all these forces were unified against it, wouldn’t it have been easier/quieter to strangle the UAPDA in its cradle, before it even made it to the House?

Did something change in the interim, to cause this pushback, only in the House? It wasn’t Grusch; the Schumer Amendment came into the NDAA after Grusch came out. The Ukraine war had already been going on. Let’s hope this pushback doesn’t reflect a sudden need to use these exotic technologies over Israel.

Can somebody tell me why this is only going on now?
