AI broke the brains of many people. The internet isn't a monolith, but prior to the AI boom you'd be hard pressed to find people who were pro-copyright (except maybe a few who wanted to use it to force companies to comply with copyleft obligations), pro user-agent restrictions, or anti-scraping. Now such positions receive consistent representation in discussions, and are even the predominant position in some places (eg. reddit). In the past, people would invoke principled justifications for why they opposed those positions, like how copyright constituted an immoral monopoly and stifled innovation, or how scraping was so important to interoperability and the open web. Turns out for many, none of those principles really mattered and they only held those positions because they thought those positions would harm big evil publishing/media companies (ie. symbolic politics theory). When being anti-copyright or pro-scraping helped big evil AI companies, they took the opposite stance.
