KOSA is a VERY BAD bill and by all means oppose it, but I'm not particularly worried. Most of the estimates say it has a very low chance of passing (and moreso now that people are pissed). What I WOULD recommend is this: https://yellat.money/ . This all happened because a handful of people whined to Credit Card companies. Well, that's certainly something the broader community can do too, and we have a lot more the 1000 people. Call the support lines, call the ethic lines, flood every method of contact they have. Supposedly their phone lines were swamped over the weekend due to this.
Still doubtful, but if anything is going to have an impact, I think this is it. I want to be clear about my own potential hypocriticalness here: I haven't done any of this yet. I am very tired, and very busy right now with all this. But this is the internet: I'm sure there are quite a few people out there with LOTS of time on their hands and nothing to do. Well, here's something to do, if you'd like.
