There is absolutely nothing “vile” about quote tweets. When used properly, it is used to enrich a discussion. It’s not just because some idiot minority abuses a feature that it should be removed entirely. If well meaning people look at two different systems, and one of them is arbitrarily gutted of useful functionality, guess which one they will choose?
Sure, at the surface level of tweeting back and forth, there is nothing vile. But the very act of using the platform funds an agent of chaos that is doing very real harm, and to ignore that because it is inconvenient is at the most charitable interpretation a selfish and callous act. There are other means of discourse, and those with input that is valuable will follow you.
