That assumes the company's behavior is rooted in ineptitude rather than malice, which is too generous at this point.
It's ineptitude. Of course it is. Otherwise it would be indefensible.
EDIT in which I clumsily express my weariness at hearing some of the smartest people in the world claim they “didn’t know” because they have arbitrated foolishness against liability
I'm not sure what Twitter's specific reasons are, but AFAIK the general trend of login-walling services over the past few years has happened due to a court decision saying that it's legal to scrape publicly available data ( https://en.wikipedia.org/wiki/HiQ_Labs_v._LinkedIn ). If they gate content behind a login wall and put a clause in the EULA forbidding scraping, this lets them use the CFAA to go after anybody who still scrapes the site.
