People say things for reasons, and those reasons aren’t always to express the true state of things. For example, it’s powerful to capture positive social sentiment around socialism without having to actually relinquish any power to the working class. It effectively destroys workers’ ability to communicate effectively about what we want to see in the world.
Back in the day, you could simply say “I’m a socialist” and that meant that you advocated for a system where workers owned the means of production, and private property didn’t exist. Now you can say the same thing, and what does it mean? Literally nothing, it’s an incoherent thing to say because it has too many contradictory meanings.
I still identify as a libertarian socialist, but every other person I talk to doesn’t understand what I mean by this (pro-China? pro-Bernie? interested in dismantling private ownership? want to slightly increase taxes on corporations and implement universal healthcare?). Most people that use the label libertarian socialist align with the original definition of socialism, and I find value in that. However for the purposes of communicating to people who don’t agree with the position, it’s effectively useless.
Destroying that avenue to communicate was definitely intentional, it subverts actual organizational efforts. The same thing has happened with unions. Essentially the entire 19th century socialist movement has been systematically destroyed through propaganda and language manipulation.
