Tit for tat is the most effective counter-strategy for unwanted behaviour. The political establishment had years to modify its behaviour and did not. Everyone who has overtly influenced government and politicized non-governmental institutions showed the way. Was it reasonable to expect the political right would remain so apathetic forever?
All Musk did was highlight the bill, and then a bunch of people crawled all over it and described what they found, and then a bunch of people let politicians know how they felt about that. Of course it was full of antagonistic provisions, and of course a crowd-sourced effort backed by modern communications spins up quickly. For every "what about the aid funding?" there is a "why was it necessary to hold that up until it could be packaged with a 40% raise for politicians?" The era of passing a bill to find out what's in it may be (at least partly) over.
A so-called "clean CR" should be possible in under 50 pages - maybe under 25 - instead of 1500+.
